CYPRESS, Texas (KTRK) – The Harris County Sheriff’s Office tentatively identified the three people whose bodies were found in a burning house in Cypress on Sunday as a woman, her adult son and his partner.

On Monday, the HCSO released the names of three people who died in a home in the 14600 block of Plains River Drive: Kelly Masciarelli, Kolin Foster and Cameryn Richard. Investigators believe Masciarelli and Foster were mother and son, and all three people lived in the home. Their ages were not released.

The sheriff’s office also said that fire investigators believe the fire may have been deliberately set using an accelerant and that the victims died before the flames broke out.

Investigators are trying to identify a suspect, but have not yet announced who that might be. It was also unclear if anyone else was in the house. The HCSO is already treating the case as a homicide.

ORIGINAL STORY: Officials suspect house fire was deliberately set after three people died

“Unfortunately, we’ve seen this before: someone commits a murder and then sets fire to cover their tracks,” HCSO Sergeant Michael Ritchie said Sunday.

Investigators told Eyewitness News of possible clues, including a red Chevrolet Corvette parked in front of the house. They said Foster purchased the vehicle, which authorities towed as evidence.

A neighbor also reported hearing a car door slam early in the morning but did not recognize the driver.

McKenzie Abbott told ABC13 she has known Richard since middle school and they are “like sisters.”

“She was a great person,” Abbott said via Zoom from her school in Virginia. “She had a really big heart.”

ABC13 also spoke to a family member of Masciarelli and Foster. The relative said both were “really good people.”

Ritchie said they were reviewing video footage as part of the investigation.

The HCSO asks anyone with information about the case to contact the Homicide Unit at 713-274-9100 or Crime Stoppers of Houston at 713-222-TIPS (8477).
