UPDATE: ATF doubles force in Dick Bruhn fire investigation.

UPDATE: ATF's trained dogs did not find any victims inside the now-destroyed building or evidence of accelerant being used in the fire. The city has also reopened the 300 block of Main Street and West Alisal Street between Monterey and Salinas streets to traffic.

As part of the Dick Bruhn Building fire investigation, expected to stretch several weeks, the Bureau of Alcohol, Tobacco and Firearms doubled its investigative force on Wednesday and brought in trained dogs to sniff out possible cadavers or accelerants inside the destroyed building.

Salinas Fire Battalion Chief Sam Klemek says four ATF investigators will be on scene and examine evidence that includes a recovered Porsche (built from a kit) with an empty gasoline tank, as well as surveillance video from nearby stores and witness reports.

But before dogs and firefighters can explore the perimeter, structural engineers are reassessing whether the remaining brick shell of the building is sound enough to investigate. Wednesday’s windy and stormy weather has already blown off parts of the destroyed roof onto West Alisal Street.

If structural engineers deem it safe, four dogs—two assigned to find possible cadavers, and another pair to detect potential accelerants that may have sparked the fire—will explore the area.

“We are 90 percent sure there are no victims, but we want to make sure,” Klemek says.

Other developments on scene include fencing going up around the scorched building to further protect the public from potential burned bits falling onto the street. Klemek also hopes to reopen one lane on the 300 block of Main Street to traffic, as well as the westbound lane on West Alisal Street.

Klemek says the police department currently has custody of the building and that the building’s owner Gerry Kehoe has been “very cooperative” with the investigation.

Just yesterday, the Weekly reported the Monterey County District Attorney’s Office has been investigating Kehoe for about a month on suspicion of illegally removing and dumping of asbestos.

“We know there are asbestos in there,” Klemek says. “But a lot of water used to put out the fire mitigated the asbestos effect. When it gets waters, it helps put it down like dust.”

The fire that destroyed the iconic Bruhn Building started about 3pm on Feb. 13. Witnesses report seeing at least four men run from the back of the building, pausing to lock a padlock, as smoke began to billow.

At the height of the fire, more then 200 firefighters were on scene. A high-rise strike team from San Francisco was asked to remain on call, as Salinas fire officials feared embers from the blaze would ignite surrounding buildings.
