CHANDLER, Ariz. -- The owner of a Chandler home that blew up late Sunday night tells 3TV he has no idea who would have done this to him.

Francisco Guerrero, 62, said he lived alone in the home near Cooper Road and Chandler Boulevard. Luckily, he wasn't home when his house blew up. He says he was out at a restaurant.

Chandler police are calling the explosion deliberate and suspicious, but they do not consider Guerrero a suspect. They believe the blast was the work of an arsonist.

"Homes don't just explode," Chandler police Sgt. Joe Favazzo said.

Investigators have been able to determine an "ignitable liquid" was used to cause the blast, which was felt by neighbors blocks away.  Roughly 100 of them called 911 shortly before 11 p.m. Sunday, when they say their walls shook.

No one was injured in the explosion, which leveled Guerrero's home and heavily damaged a home next door.

"I've never seen anything like this, and I had fire fighters coming up to me saying the same thing," said Detective Seth Tyler of the Chandler Police Department.

Samples of the charred rubble have been sent to the Arizona Department of Public Safety to be tested.  Investigators say those tests should reveal what kind of flammable liquid was used to ignite the blast.

Chandler police say it's too early to know if Guerrero was specifically targeted, but they do not believe neighbors should be concerned.
