In the early morning hours of Monday, May 26, 2014, sheriff’s deputies responded to reports of possible gun shots and a male yelling in the area near Pacific Hills Road, Mission Viejo.

Following the preliminary death investigation by the Coroner Division, this report appears consistent with the estimated time of death; however, autopsies are still pending.
