Adriana Coronado's mother speaks

Family and friends are mourned the loss of Adriana and Casear Coranado, a father and daughter shot to death early this week. Adriana's body was just identified on Friday.

It all started Monday, when Casear Coronado's body was found in Walker County. It didn't take long for an Amber Alert to be issued for his daughter, who was believed to be with him at the time of his murder.

Saturday family and friends mourned their deaths.

The Walker County's Sheriff's Office released surveillance video Thursday of a person-of-interest leaving the father's truck in Conroe on Sunday night.

Investigators have said they don't have a motive and don't know what Coronado was doing in Walker County.
