AVONDALE, Ariz. (AP) - Police in Avondale say three people had to be hospitalized after a chemically-triggered explosion that blew the garage door off a home.
Sgt. Brandon Busse says two men and one woman were taken to a burn unit in Phoenix early Sunday for injuries that weren't life threatening.
Busse says the two men were working with some type of chemical in the garage around 1:30 a.m. when the woman entered with either a lit cigarette or one that she was about to light.
Busse says the damage was all contained within the garage.
He says two adults and three children who were elsewhere in the home were uninjured.
Authorities are still investigating the exact cause.
