A late-night house fire in San Marcos has led to the arrest of a 33-year-old local resident on suspicion of murder and arson, authorities confirmed.
Luis Alvarado of San Marcos was taken into custody Sunday following an investigation into a residential blaze that claimed the lives of two people. He faces two counts of murder along with an arson charge. After his arrest, he was booked into the San Diego Central Jail and is scheduled to appear for arraignment Thursday at North County Superior Court.
The fire was first reported at approximately 11:45 p.m. Saturday near the 900 block of Lacebark Street. Emergency crews responded quickly to the scene, where flames were visible from the second floor of the home. Firefighters worked to contain the blaze and conduct a search of the property.
During their response, first responders discovered two individuals deceased inside a second-floor room. Officials have not yet released the names of the victims, pending notification of next of kin. The exact causes of death remain under investigation by the San Diego County Medical Examiner’s Office.
Investigators from the San Diego County Homicide Unit examined the scene throughout the weekend. Authorities have not disclosed what led them to identify Alvarado as a suspect or whether the victims were known to him. Detectives are continuing to gather evidence and determine the circumstances surrounding the fire.
The incident has left neighbors shaken, as the residential area is typically considered quiet. Officials have not indicated whether there is any ongoing threat to the public.
