White Rock-area fire that killed woman, dog now labeled homicide
The victim in the suspected homicide has still not been identified.
Dallas Fire-Rescue officials said they got a 911 call and arrived to find fire coming from an RV that was parked next to a house.
The RV was destroyed and the one-story home was damaged.
Firefighters found McBride’s body inside the RV once they knocked down the flames.
Two people inside the home were able to escape and were not injured.
Dig deeper:
According to an arrest warrant affidavit for Richardson, investigators determined an accelerant was used to start the fire.
They also obtained video from a security camera that allegedly shows Richardson carrying a container of accelerant, igniting the RV, and then fleeing the scene in a Kia sedan.
The affidavit states McBride had filed a police report the day before her death because she’d been robbed by a man in a Kia sedan. The suspect had taken the keys to her RV.
Arson arrest made in fire that killed woman, dog in White Rock area
A suspect has been arrested in a White Rock area fire that's been investigated as a homicide since October.
Investigators found more video of the Kia sedan driving through the neighborhood throughout the week and used the license plate number to track down Richardson.
They determined the car had been rented by Richardson’s mother in Minnesota, where he’s from.
Data from the car’s GPS, along with images from additional security cameras between Dallas and Minnesota all placed Richardson at the crime scene, the affidavit states.
What we don't know:
Police have not yet released details about how Lewis and Grindberg were linked to the crime.
There’s also no word yet on a motive for the murder.
