William H. Thomas, 37, was arrested Wednesday on suspicion of burning a Rio Linda woman in a North Highlands manufactured home last month.
The Sacramento County Sheriff's Department believes Thomas lit a mobile home on the 7500 block of Costa Mesa Circle ablaze on April 1 while Aryanna Lynn Doyle, 28, was inside. Doyle's body was found by Sacramento Metropolitan Fire District first responders at the scene, according to a Sheriff's Department media release.
Thomas was already in Sacramento County Jail custody on two other arson charges when he was arrested on suspicion of murder and arson in connection with Doyle's death, Sgt. Shaun Hampton said.
Doyle and Thomas were acquaintances, Hampton said, though he declined to elaborate on the nature of their relationship. The woman's body was identified by her husband, Joshua Doyle, according to the Sacramento County Coroner's Office.
Thomas' criminal history in Sacramento County includes being convicted or pleading no contest to battery with serious bodily injury, assault with a deadly weapon, reception of stolen property, two counts of corporal injury to spouse and two counts of resisting arrest.
Hampton said he did not know whether Doyle was burned alive or killed before the home was lit on fire. No other suspects are currently being investigated in her death.
