When the shooting stopped and three cars sped away from the Indianapolis home Sunday afternoon, more than 70 shell casings were found at the bullet-riddled residence of Indianapolis Colts assistant coach Parks Frazier.

Investigators also found a silver iPhone in a purple case that may have been left behind by one of the shooters.

The shooting happened shortly before 6 p.m. on Mother's Day in the Sunningdale Commons subdivision, near The Country Club of Indianapolis.

The home was unoccupied at the time, but multiple neighbors who were home said that eight people arrived in three cars before opening fire, according to IMPD police reports. A rear door to the home was also kicked in, and shots were fired inside.
