On Friday, the Fort Bend County Sheriff's Office said Austin Mapes was booked into the county jail on a criminally negligent homicide charge and given a bond of $100,000.
It all started on Aug. 22 at a home on Bent Grass Drive in Katy. Investigators said deputies responded to a shooting and found 18-year-old James Wisniewski shot to death.
Investigators said Wisniewski was a guest at the home, but it is unclear whether Mapes knew the victim or what led to the shooting.
"This is truly a tragic incident," Sheriff Eric Fagan said. "Our thoughts and deepest sympathies go out to the victim's loved ones during this difficult time."
