EL MIRAGE, ARIZONA - On September 24, 2018, Frank Gallas Mendoza was arrested by authorities in Fresno, California for the 2001 murder of El Mirage resident Richard Cacero Lucero. On December 20, 2001, El Mirage police conducted a welfare check at the residence of Richard Cacero Lucero at the request of a family friend. Officers gained entry to Lucero’s home and found him deceased.
Arizona Department of Public Safety (AZDPS) detectives were asked to take over the death investigation due to the AZDPS’ available staffing and resources. The Maricopa County Medical Examiner’s Office determined Lucero’s death was a homicide. The case eventually went cold after AZDPS exhausted all leads and investigative techniques available at the time.
