Firefighters are once again investigating what led to a fire at a northeast Fresno mobile home park.
The fire sparked at the Trails End Mobile Home Park on Sierra Avenue and Clark Street shortly before 10:00 pm.
Firefighters got an initial call about a tree on fire. When they arrived, they saw the flames spread to two trailers and moved toward a third.
Investigators say residents heard electrical noises before the fire broke out.
Two of the three mobile homes that caught fire are a total loss.
No one was hurt, but one person was checked for smoke inhalation.
Fire crews also rescued a dog and several cats. The SPCA was contacted to help with the animals.
"The main challenge was to contain this fire from burning multiple homes. Fortunately, we held it to three, which is a significant challenge," Fresno Fire Battalion Chief Sean Johnson.
