It may take some time for investigators to determine what caused a bus to crash on the north side of Indianapolis Saturday afternoon.
The bus was returning from a summer camp in Michigan when it overturned while exiting Interstate 465 onto Keystone Avenue. Chad and Courtney Phelps, their unborn child, and Tonya Weindorf were killed. Dozens of teens were injured.
The bus driver, 68-year-old Dennis Mauer, has said the brakes on the bus failed and he was unable to stop.
Indianapolis Public Safety Director Troy Riggs says investigators must examine the bus “bumper to bumper” to determine if human error or mechanical failure caused the crash. He says investigators plan to look at “every mechanical part on that bus.”
“There’s a lot of people who look at this,” he says. ”At the end of the day it’s in our jurisdiction. We have mostly responsibility there and will be working through this with that team.”
Chad Phelps served as the youth pastor and was the son of the senior pastor at the church. Tonya Weindorf was traveling with her child who survived the crash. Several others were taken to area hospitals for treatment.
The charter tour bus was owned by Colonial Hills Baptist Church.
