Avondale Police are investigating a homicide case in Litchfield Park, Arizona, following the discovery of two decomposing bodies buried in a residential backyard. The investigation began on Tuesday when relatives requested a welfare check for three residents at the home: a husband, his wife, and their adult son, 27-year-old Matthew Flores. Upon arrival, officers found the house empty but discovered signs of potential foul play, including a large amount of blood and evidence of an attempt to conceal it. This prompted an immediate missing persons investigation. On Thursday, authorities announced that two unidentified bodies had been recovered from the yard, confirming the case is being treated as a homicide. Matthew Flores is now considered an alleged suspect in the deaths. Police believe that Flores fled the United States prior to the welfare check on Tuesday. The names of the deceased husband and wife have not been released at the family's request. Authorities have stated there is no known threat to the general community but are urging anyone with information regarding Matthew Flores' whereabouts to come forward. The Avondale Police Department is actively seeking tips to locate the suspect. Residents with information are asked to contact the Avondale Police Department directly at 623-333-7001. The investigation remains ongoing as police work to determine the full circumstances surrounding the deaths and the suspect's escape.
