Accident while riding off-duty, triggered by a bike mechanical failure, possibly a fork failure, resulting in a head injury.

"He was a biker from age 6 on. And he was happier than he had ever been at the time he passed away." -Sean's mom, Alice McCash

Sean was a constant in The Critical Mass beginnings and made his mind up to be there every time the Mass swarmed.

Sean was a very well respected and loved Bike Messenger for Service First Courier at 1132 W. Grand Ave. After working his ass off as usual on a Friday night he was heading home.

They said from the Police report that he stopped to fix a rear flat and while he was kneeling he was hit in the head by a car bumper at the posted speed of 30 M.P.H.

The driver kept going, and was never charged or found. He just kept going.

He languished for 4 days in a hospital before succumbing to his injuries.

Anyone who knew Sean McCash knew he was fast! Accurate as a bullet. He was a go to Biker for Service First Courier and I was proud and blessed to be his Dispatcher.

Sean attended the Illinois State School of the Arts in 1996.  He was an enthusiastic and engaging student as well as a charismatic classmate. At the time Sean had a fondness for punk music and frequently played in his own band, the Ronald Rayguns. Sean was proud of his hometown and invited me and several others to stay with him in Olney, Illinois. He was especially proud of his mother, of whom he spoke often and well.
 
It has been many years since I last visited Sean and I am grieved that I will never visit him again. But I want people to know what I know of him and honor his memory. Sean always had a smile on his face and went out of his way to make those around him feel welcome. He was sometimes prone to antics that were endearing in their innocence. His energy was incredibly positive and he brought compassion, sincerity, and love into this world. 
 
He is and will continue to be missed.
