Brennen was always such a kind soul! i’ve gone to school with him since 3rd grade and hearing this broke my heart i’m so sorry to your guys family🙏🏽❤️
Mrs. Bittner was one of my absolute favorite teachers in elementary school, i remember the day i realized that Brennen was her son. All of my memories of Brennen are of him cracking jokes and always smiling; though him and i weren’t close i was so sad when i found this out and can see that he grew into an amazing person. Praying that all of his family and friends are surrounded by endless love and support, i’m so sorry 🙁 ❤️❤️
He was in many of my classes in highschool when I was a new kid there we were never close friends but he was so nonjudgmental and the moments we did share were good ones rest in piece Brennen
Brennen was my friend through almost every stage of life. We started middle school together, both looking at it as a fresh start and ten years later, we were just months away from graduating college together in Cincinnati. He was truly one of a kind an amazing friend with a heart full of kindness and a laugh that could light up any room. Some of my absolute best memories in life are with Brennen. When we were younger and couldn’t drive yet, we’d walk everywhere, talking about everything and nothing. Once we got our licenses in high school, those conversations just moved to the car. And even in college, I’d drive him home for breaks, and we’d talk the whole way just like always. Now in college, we lived just around the corner from each other. I know Brennen will always remember Moerlein ave. It felt like we had come full circle back to walking to each other’s houses, the library, or even the bars for a night out. I can’t put into words what a loss this is. I’ll carry the memories of our friendship with me for the rest of my life. I will miss Brennen deeply. Wishing so much love to anyone who knew and loved him. My thoughts and prayers are with your family now and always.
The Johnston family is heartbroken and sends prayers from Florida, Wyoming, Colorado and Virgina.
Im so sad to hear this..
I went to school with Brennen for awhile, he was one of the first people I met in 3rd grade. Always the sweetest, funniest kid. Always smiling ear to ear literally, we’d laugh about any and everything together.
We talked not too long ago and he was telling me what he was going through, I knew he would make it through!! He was such a light.
To his family, I am so sorry, sending hugs and prayers to all of you.
