Police are searching for a suspect in the brutal beating death of a woman in a southwest valley neighborhood. Metro Homicide Lieutenant Lew Roberts says the unidentified victim's body was discovered Wednesday afternoon inside a sport utility vehicle parked outside a home on Mangrum Circle, near Rainbow Boulevard and Spring Valley Parkway. Roberts says the suspect may have used a rock to beat the victim, but there is also a possibility she may have been strangled. Several people witnessed the attack, and authorities are now searching for 32-year-old Jesus Munguia. He was last seen driving away from the murder scene in a white Honda Civic. It's unclear if Munguia was the victim's boyfriend. If you have any information that can help, call Metro or Crime Stoppers at 385-5555.
