    I taught Jason in Middle School and remember him as one of my very favorite students. He was hard working, kind, compassion to others and extremely humorous. He will always remain in my thoughts, prayers & heart.

    It’s been a long time, matter of fact very long. The time and distance that is between our friendship does not impede on the memories we have shared together. There are so many moments that I can remember vividly as it was yesterday. You were always there for me through the worst situations and the best ones. I can honestly say that you are one of my true friends. No one could make me laugh like you did, no one could bring the smile to my face that you did and above all no one could be a brother to me like you did. You were an amazing person and a better family man. You always made me feel like apart of your family no matter what. I remember when we were really young, you and I would get in so much trouble together. I remember jumping the fences to Kodak and breaking into buildings on kodak property when we were the age of 7. We would just laugh when we got into trouble. We never had a worry in the world. If I could take one thing away from you that I have learned it would have to be that family is the most important thing in life and treasure it to the fullest while we are with them. You will be missed by me Jay-bird, and many others. You will be in my heart, in my thoughts, and in my prayers 4ever. I love you man and I will see you again.

    Dear Brother, You have no idea the void that is left in this family now that you are gone. You are my baby brother and it is my job to watch over you. Now it is your job to watch over us from heaven. The only peace that we can find is in knowing that you are not in any pain anymore. Our hearts are breaking and we don’t know what to do with all of this pain. We will carry our memories of all of those happy days we were able to spend with you till the day that we can see you again. We LOVE you more than you could ever know, RIP my dude. Your Landawg and Journee Girl miss you so much too. Sending so much love up to heaven right now, your Brother Bobby and Sister James.

  10. Afton on December 8, 2013 at 8:37 pm

    Rest in peace my friend ….. So many memories growing up just rush to my head. I just want you to know you are in my thoughts, my prayers and my heart as well as your family. Now you are free

  11. amy gifford on December 8, 2013 at 10:08 pm

    I am so sorry that we lost touch so many years ago. You were a true friend throughout middle and high school; not just to me, but to everyone you met. You were truly kind to everyone, even those whom didn’t get the same respect from many others. I’ll always remember your kindhearted nature, and the way you would go above and beyond to make me laugh even in my darkest days. You were the eternal optimist – I always looked up to you for the way that you could see the silver lining even in the blackest cloud. I am so sorry that you lost that optimism and that hope. My thoughts are with your family, especially your beautiful children. I’m sure you’ll always be looking over them.

    Until we meet again,

  13. Jackie Oliveri on December 9, 2013 at 2:41 am

    Dear Jason, my daughter told me about your passing. I didn’t know you except through my daughter being one of your classmates. My heart aches and I am so sorry. I pray for you your loving parents and beautiful children. You will forever be in their hearts. Jackie

  14. Michael Leisten on December 9, 2013 at 4:40 am

    Rest easy MY BOY we’ve got it from here.
    Love and miss you now and forever

  15. Joe Doty on December 11, 2013 at 12:09 am

Jay you will be dearly missed by more people than you realize. We will never forget you and will always stand by your family when they need it most. I won’t say goodbye, Ill just wIt to say hello the next time we meet. Rest in peace buddy.

  16. Gina Alessi on December 11, 2013 at 1:40 pm

    I still cannot believe you are gone. The night I found out it seemed like all of the memories came flooding right back. You are someone I have known since we were young, so many memories. Good, bad, happy, sad, fun! You always had this smile on your face and always had the ability to make people laugh and smile on the worst of days. My heart breaks for you, your family and of course your kids. Your memory will live on forever, through your beautiful children and the many memories that many people have of you. I will continue to keep you and your family in my thoughts and prayers. I want you to know that even though we have lost touch the past few years you will remain in my heart and I know you have no more suffering and pain. To the family….I am very sorry for your loss and im sure Jason will always be looking over, guiding and protecting your family.
    Im so sorry. Until we meet again Jason.

  17. Aunt Cheryl on December 12, 2013 at 12:48 am

    Even tho we lost touch these couple of years, I believe you always knew I will always be here for you and the family. (my family) for life. Watching you and all the kids grow up was such an awesome experience. The only thing holding everyone together is knowing you are not in pain anymore. I love you Jason. xo

    To Jason’s Family and Friends,

    I am so sorry to learn of Jason’s passing. I saw his picture on this site, and still see in that grown man the smiling, kind seventh grade social studies student I taught. It really seems like yesterday he was in my classroom. I will always remember the special person I saw then. Know that so many saw that in Jason as well. He will not be forgotten.

  19. Dorothy DeLorme on December 12, 2013 at 10:33 pm

    Jason, I feel like my heart is bleeding,you have no idea. I loved you and you always thought I didn’t. You always asked your Mom why I didn’t love you, and it would really upset me that you would feel that way. Yes, I was upset with a lot of the things you did, but we all know you were fighting a fight that you could not win. You put up a good fight Honey and we all know that. I so wish you would have told someone of us just how troubled you were.We love and miss you more than you can begin to imagine. You worry about your Mom, and I want you to rest easy, knowing I will do all I can to help her in her sorrow, and she knows you are watching down on her. Jason, I love you and miss you terribly. You party hardy honey, and we will all be together someday. R.I.P. Love you

  20. Joseph Mastowski on December 12, 2013 at 11:01 pm

    So many things to say. Was afraid of this day since I was 6…remember doing everything in my power to prevent something from happening to you. Thought that when you celebrated your 21st birthday that my job was done. Feel like I should have tried longer, that maybe I could have stopped it. Got wrapped up in making my own family and somehow screwed that up too. You never did listen to me though..Aeris and I saw you just a few hours prior..I told you not to do anything stupid..you promised you wouldn’t. I forgive you for that…and forgive you for everything. And your debt with me is cleared..I wont collect nor mention it when we meet again…which will be in another 34-35 years…but I hear you and feel you around…making your rounds..do have some questions for you so when you feel the summons..stop by and speak loud and clear into my recording device…now I might not have acted like it at times…even talked down to you..but you know I always loved you…we will meet again..but not yet…not yet..

    To My Beautiful Son
    I dont even know where to start or how to do this at all for that matter. How can I tell you now how much I miss you, how much I love you, of course you knew that, we told each other that every day, I miss your phone calls, I miss you telling me constantly how much you loved me, if I could just hear it one more time, but then I know even that wouldnt be enough; I would want to hear it over and over again until the day I die. Jason, I wish you could let me know why, why didnt you tell me you were suffering so badly, I would of done anything i could to help you and you know that, you just spent so much time worrying about me that you didnt stop to think that I would help you. We spent so many years thinking we were helping each other, and it ended up it was probably your biggest downfall, for that I will be forever sorry honey. I might of been your biggest enabler, but I just couldnt give up on you, I just couldnt. I wish I could of let you know how you meant the world to me, you were my baby and I just feel so lost without you, life will never be the same. They tell me I will feel better someday, that I will smile again, that the pain will lessen, I dont think so. When you died you took the humor out of my life. Did you see the party that was thrown in your honor? Jason it was beautiful, there were so many people there for you baby, it was all for you. You were so loved and I am just so sorry you never knew it. Honey, I hope your pain is gone, I hope that God is holding you close right now,because I cant, please dont worry about me anymore honey, something good is going to come out of this, God only knows what, but something has to. God couldnt take such a wonderful man, with such potential and such a zest for life when you werent fighting the demons, a man who lived for his children and his family without there being a good reason. Honey, you watch over all of us from the skys, we will all take care of your babies for you from here. I know how you wanted things done with them, and so does Jenn and she is picking up where you left off I can assure you of that, I have never been more proud of her. Her heart is broken for the love that once was and she misses you so bad, and so do those babies.. Baby, I love you and things just will never be the same, I want you here with me so badly that it hurts so bad.. I will smile again one day when I think of all the great things you did and the way you use to love to make me laugh, make me cry, and no one will ever take that bond away that we had, not even death..Until I see you again baby boy, keep em laughing up there, give auntie Imogene a little tug on her chin from me, and your great grandparents Kisses and hugs from me, but save the biggest and the best for me, I love you honey, more today then yesterday, but not as much as tomorrow, Soar with the birds..Love Mamadukes…

    You were my friend who I looked after and I helped out when you needed it. I absolutely cannot fathom that you passed away. I hadn’t heard from you in a long while and I thought you may have moved or gotten married. I just checked online (something told me to check 3-22-14) I am completely saddened by your death. I am in an utter state of shock. I wish I could have talked to you one last time. R.I.P. my friend. You will be in my memory.

  24. Michael Borrino on March 27, 2014 at 12:05 am

    I left the last condolence to Jay on this page. I’m not sure any of Jay’s family or friends come to this page but, I was hoping someone could contact to me about Jay’s passing.(maybe Michael Clark who I think mentioned me to him) I feel deeply saddened about the loss of Jay. I hadn’t seen him in a few months and feel so horrible about his death. You can email me @ mborrino@rochester.rr.com or call me at 585-336-9806. I just would like to talk to somebody about Jay and what happened. I gave Jay money, food, work and shelter over years and I just was hoping to get a little closure about his death. I know it will be random if someone sees this but I really just would like to know about Jay’s last couple of months.
