A bizarrely dressed suspect is suspected of killing a 92-year-old millionaire developer inside his Southern California beachfront home, then barricading inside for hours during a SWAT standoff, according to authorities.

Police in Hermosa Beach say officers were called to a residence in the 500 block of The Strand just after 12:30 p.m. Saturday for a welfare check after the elderly resident had not been seen for several days.

What began as a routine call quickly escalated when officers entered the home with a property manager and encountered an uncooperative individual inside who claimed to be armed and barricaded themselves, according to the Hermosa Beach Police Department.

SWAT teams from multiple agencies, along with crisis negotiators, responded to the scene and worked for hours to secure a peaceful surrender. The suspect was taken into custody roughly seven hours after the initial call.

After obtaining a search warrant, officers located an adult male dead inside the home. 

The victim was identified as 92-year-old Demetrius Doukoullos, a longtime developer who lived alone at the beachfront property, according to the Los Angeles County Medical Examiner. The office lists the cause of death as deferred, pending further investigation. The Los Angeles County Sheriff’s Department Homicide Bureau has taken over the investigation.
