Lt. Ato McTush of the Indianapolis Fire Department said the dead
included a man and a woman, but he did not have information about the
third victim.       

Witnesses said the bus came speeding off Interstate 465 on Saturday
afternoon, struck a retaining wall as it tried to round a curve and
overturned. A local TV station, WTHR, reported that the bus driver told witnesses his brakes had failed.       

A witness, Duane Lloyd, told the TV station that he heard a loud noise
behind him as he was traveling near the intersection and saw the crash.
      

“I heard a skid, I looked back, I see this bus in the air and people
falling out of the bus,” Mr. Lloyd said. “I could have gone my whole
life without seeing that.”       

The bus was carrying 40 passengers who are members of Colonial Hills Baptist Church in Indianapolis
