On August 6, 2020, at approximately 2129 hours, Cathedral City Police Department (CCPD) officers were dispatched to Century Park (located at 30555 Davall Drive in Cathedral City) regarding a physical altercation with subjects fleeing the area.  Upon arrival, officers located an unidentified male victim with life-threatening injuries.  CCPD officers immediately started CPR and life-saving efforts until Cathedral City Fire Department Paramedics responded to the scene and transported the victim to an area hospital.  Unfortunately, life-saving efforts were unsuccessful – the unidentified male succumbed to his injuries, and was pronounced deceased at the hospital.  The deceased was later identified as Ruben Mujica, 29, of Palm Desert.

Cathedral City Police Detectives were called to the scene and initiated a homicide investigation.  For the last three weeks, Cathedral City Detectives have worked tirelessly as the case began to focus on Rena Alaniz (20, of Thousand Palms) and her biological father, Carlos Ruiz (40, of La Quinta) as being principals in the murder of Ruben Mujica.  Through a very detailed and thorough investigation, Cathedral City Detectives linked the victim to the suspects through various types of evidence and statements.  Cathedral City Detectives secured homicide arrest warrants for Alaniz and Ruiz, and continued to gather evidence against both suspects.
