Fire investigators say after analyzing surveillance video and using information from witnesses, they named 21-year-old Zach Benali a suspect.
In fact, officials say he went to the police department Friday at 3 a.m. and told them it was an accident.
However, through specific questions and physical clues, investigators realized Benali was responsible for the fire.
"We asked him, point blank, ‘Were you burned?'" said Grapevine Deputy Chief Fire Marshal Randie Frisinger. "And he says no, and he provided us with information that corroborated what we already saw on the video."
The fire marshal says just before 9 p.m. Thursday, two men broke through a secure fence and while burglarizing portable storage buildings at the Grapevine Relief & Community Exchange, or GRACE, one of them started a fire, causing $75,000 worth of damage.
A judge signed an arrest warrant Friday night, and Benali was taken into custody a short time later.
GRACE helps 5,000 people a year with things like food and housing to employment training.
A volunteer cleanup will happen Saturday at 9 a.m.
