The child’s age was not immediately available.
Firefighters found the two after being called to the blaze at 1592 Beulahtown Road.
Officials said the fire started when Matthew was playing with a lighter on a bed.
Firefighters were called to a fire at the Laton House in Nashua’s Railroad Square late Sunday night.
The apartment building was evacuated, sending at least 50 people outside, officials said.
Fire officials said two people were hospitalized with minor injuries.
The fire started on the fourth floor, but the cause is under investigation, officials said.
But hours later, around 9:30, surveillance footage caught a different crime scene. This time at the Brookview Apartments. Someone called 911 after a fire started in one of the units. The sprinkler system extinguished the fire before it spread.
•Dispatch: Hello
•Caller: The water is coming down? Okay. The fire is out now. We had to turn off the sprinkler system. I don’t know, someone burned the apartment down. Someone, I am not sure.
Firefighters says they later found a pile of laundry on a bed, dowsed in lighter fluid.
That apartment belonged to Cox mother according to investigators.
“They were in route to the scene when the police department called them and said that they had a person of interest that they needed to come talk to,” says Deputy Chief Mike Wilson of the Norman Fire Department.
Cox had been tracked down by officers who were using images captured hours earlier by the cameras at the Alameda shopping center.
“When our investigators showed up, he confessed to the investigators that he was the one who started the fire. Wanted to make sure no one was injured in the fire he started,” says Deputy Chief Wilson.
Cox will be in court next Tuesday.
He faces one count of First-Degree Arson and Four Counts of Malicious Injury to Property Over $1,000.
