Airman Calvin Cooper, 22, faced sentencing Wednesday after being convicted Tuesday of involuntary manslaughter and negligent homicide in the death of Angelica Baca, 39.

James Dallas Wicker, a brother of Baca, said Cooper’s conviction doesn’t bring his sister back but was “the start of a long healing process,” the Albuquerque Journal reported.

A prosecutor, Capt. Andrew Trejo, said Baca was struck in a street median by Cooper’s car as he drove 60 mph in a 35 mph zone.

Capt. Victoria Clark, one of Cooper’s defense attorneys, said Baca was negligent by not using a crosswalk to cross a busy street.
