A man accused of shooting two Colorado students last week now faces 15 charges, including attempted murder, assault and child abuse.

Prosecutors formally filed charges Tuesday against 32-year-old Bruco (BROO'-so) Strong Eagle Eastwood, accused of opening fire in the parking lot of Deer Creek Middle School in suburban Denver on Feb. 23.

He faces up to 97 1/2 years in prison if convicted on all counts.

Eastwood wasn't in court for Tuesday's hearing but appeared on a video link from the jail. He said nothing, and his public defender didn't directly address the allegations.

Eastwood was initially held on two counts of attempted murder. Prosecutors had said other charges were planned.

The two wounded students are recovering.
