Florida Police Searching for Missing Mother and Daughter After Girl's Father Found with Self-Inflicted Stab Wounds

Police in Doral, Florida, are looking for a 43-year-old woman and her 9-year-old daughter, who've been missing for more than a week, PEOPLE confirms.

On Friday, officers found the girl's distraught father Gustavo Castano sitting in a truck parked outside the same Miami-area Home Depot where he told investigators he'd allegedly dropped Liliana Moreno, 43, and her 9-year-old daughter, Daniela, off on the morning on May 30.

Police claim Castano's body was riddled with self-inflicted knife wounds. He was transported to an area hospital for treatment, according to investigators.
