Marcus Crosby 35, of Joliet Township, IL, a high school security guard, had tried out for the game show with several family members just hours before the horrific murder/suicide.

However, Crosby’s wife, 35-year-old Kearra Hosey, did not accompany her husband to the tryouts.

Later that day, family members living in Crosby’s home says he and Hosey got in an argument that ended with Crosby pulling out a handgun and shooting her multiple times before killing himself.

This was not Crosby and Hosey’s first violent argument.

Last September, Hosey filed for protection against Crosby after he pushed her down the stairs during a verbal altercation…

Crosby himself had a rap sheet that included a vandalism conviction in 1998, and a criminal sexual assault charge in 2004 for which he was not tried after the victim became “unavailable.”
