DENVER (AP) -- The families of five slain Columbine students asked that a federal grand jury investigate their claims that authorities have covered up evidence that one student was killed by police.
"Lies have been told, beyond any doubt," family attorney Barry Arrington said after he submitted his request to the U.S. Attorney's Office on Tuesday. "The only issue is, why are they lying?"
The families claim an officer accidentally shot 15-year-old Daniel Rohrbough as he fled the school during the April 20, 1999, massacre.
Rohrbough's father, Brian, claims Denver police Sgt. Dan O'Shea told a school administrator he feared he may have shot a student, and that a sheriff's deputy saw the shooting.
O'Shea has said he arrived at Columbine after Daniel was shot.
At a news conference last week, Brian Rohrbough played a tape recording of a voice he identified as Arapahoe County sheriff's Deputy Jim Taylor describing the shooting.
"You could hear glass breaking, you could see kids running everywhere, and that's when I see the boy coming down the sidewalk, you know, and I see him just fall down," the voice says.
Rohrbough said the recording was made without Taylor's knowledge during a March 2000 dinner with Daniel's mother, Sue Petrone, and stepfather, a longtime friend of Taylor's.
In a Dec. 31 statement, Taylor said he didn't see the shooting and told the Petrones only what he had seen on television and read in newspapers.
