Two men are dead, one may face the death penalty, and the home allegedly set ablaze in a fatal Nov. 1 incident has been described by one city official as a longtime “problem property.”

On Tuesday, a team of officials with various city departments inspected the home at 1385 El Sereno Ave. and others under the same ownership, city spokesman William Boyer said. The duplex, where 20 men were renting partitioned rooms at the time of the fire, remains under investigation as a possibly illegal boarding house.

Also on Tuesday, the El Sereno tenant accused of intentionally setting the fire, Garth Allen Robbins, 49, pleaded not guilty to 19 criminal charges, including two counts of capital murder, 15 counts of attempted murder and two counts of arson.
