WESTMINSTER, Colo. (AP) — Friends and family are planning to gather for the funeral of a 17-year-old girl shot to death by Denver police.

A funeral Mass for Jessica Hernandez will be held Saturday at a church north of Denver, near where she grew up.

Police say Hernandez was shot Jan. 26 after she drove a stolen car toward an officer in a residential alley in Denver. However, a teen passenger in the car says Hernandez lost control of the vehicle because she had already been shot and was unconscious. The shooting is still under investigation.

The shooting sparked protests and came amid a national debate about police use of force fueled by racially charged episodes in Ferguson, Missouri, and New York City. Hernandez’s family and others have called for an outside prosecutor to investigate what happened.
