The younger Foster told his sister he felt “tired and sadness,” but he was thankful for everyone’s support.
“Don’t take life for granted,” said Foster Jr., who added drivers should never speed regardless of the circumstances.
Police have said they believe speed played a factor in the fatal crash that occurred around 7:30 p.m. Friday on Millikin Road near Butler Warren Road.
That stretch of Millikin Road, which is hilly, has a posted speed limit of 45 mph.
The crash is still under investigation, according to the Butler County Sheriff’s Office.
There were four people in the Tesla at the time of the accident: a driver, front-seat passenger, and two passengers in the back seats.
Kaylie Jackson, 17, a back-seat passenger, was ejected from the car in the accident. She died Monday, according to a statement from Monroe Local Schools.
