INDIANAPOLIS A bus carrying teens coming home from a church camp crashed Saturday after exiting an interstate in Indianapolis, killing three people and sending others to hospitals, officials said.

Indianapolis Fire Department spokeswoman Capt. Rita Burris confirmed to CBS News that three people died. Five people were trapped in the wreckage but were extricated within 20 minutes, Burris said. Some of the victims were taken from the scene by helicopter.

Fire department Lt. Ato McTush told The Associated Press the dead included a man and a woman. He did not have information about the third victim.

Witnesses said the bus came speeding off of Interstate 465 on Saturday afternoon, struck a retaining wall as it tried to round a curve and overturned.

Karen Woodard, a member of the Colonial Hills Baptist Church, cried as she stared at the wrecked bus surrounded by pillows, water bottles and clothing. She said the bus was returning from a youth camp in Michigan and that some of the teens had their parents with them.

"It's so terrible. I can't believe it," she said.

The fire department said four good Samaritans helped before first responders could arrive, including one man who helped pull the driver out.

Burris told CBS News the bus was carrying 37 passengers who are members of Colonial Hills Baptist Church in Indianapolis and were returning from a summer camp.

Those injured included children and adults, but the bus was mostly filled with teenagers, Burris said.

Roads near the scene were closed, and authorities were urging people to use caution in the area. A hazardous materials crew was cleaning up diesel fuel that spilled in the crash.

Outside the church about a mile away, families gathered to hug and talk quietly as parents paced back and forth talking on cellphones. A yellow school bus with the church school's name was parked outside with piles of sleeping bags and suitcases nearby.
