A 67-year-old man and a dog were found dead inside a home after a fire that has been deemed "suspicious" tore through a Seal Beach residence early Saturday, authorities said.
The blaze erupted at a two-story house in the 200 block of 17th Street around 12:15 a.m., according to Orange County Fire Authority Capt. Steve Concialdi.
It took about 50 firefighters about an hour and 15 minutes to extinguish the flames at the home, which was described by the captain as having a large amount of combustibles and "pack rat conditions."
Firefighters entered the single-family dwelling after the fire was knocked down and found a man and a dog deceased inside, according to Concialdi. A cause of death was not immediately provided.
The victim was later identified by the Seal Beach Police Department as John Donnelly, a resident of that city.
Other residents made it out safely from the bottom floor, and no firefighters or civilians were injured, according to the Fire Authority.
Damage to the structure and property totaled approximately $520,000.
Investigators have deemed the blaze "suspicious," authorities at the scene said. A cause was still being determined.
Anyone with information about the incident was urged to call Seal Beach police Detective Pete Krok at 562-799-4100, ext. 1110.
