Las Vegas ? The bodies of six victims of an arson fire at a downtown Reno casino-district hotel have been recovered, and crews searching the rubble could find more, officials said Friday night.

Three bodies were pulled Friday from an annex on the east side of the 84-year-old Mizpah Hotel, fire department spokesman Steve Frady said. Two others were found in the south portion of the historic building late Thursday.

“We haven’t been into the most heavily damaged sections of the building,” Frady said. “Because two floors collapsed, we don’t know what’s in that debris.”

At least 30 people were injured, three critically, in Tuesday night’s fire. Police said 60 to 80 people had been inside the 84-year-old, $150-a-week hotel, which mostly served boarders.

Investigators suspect Valerie Moore, a casino cook and paroled murderer who lived at the hotel, started the blaze by igniting a mattress.
