A San Diego woman was allegedly killed by her estranged husband who police said crashed his vehicle into their home, Us Weekly has learned. Officers found Monica Coates dead inside her master bedroom at the Bay Park house, where a fire had broken out minutes after she called 911 about the crash, according to San Diego police and reported by The San Diego Union-Tribune. She was said to be badly burned. Her estranged husband, Stephen Coates, was found alive but also burned inside the house, authorities said. He was hospitalized and charged with suspicion of murder in connection with his wife's death, according to the newspaper. The San Diego Police Department did not immediately respond to an inquiry from Us. Monica, 61, had an active, temporary restraining order against Stephen, 62, after seeking the protective measure in October, The San Diego-Union Tribune reported. In her request, she said he was "displaying paranoid ideas." "My husband believes that I am conspiring with others to kill him," Monica wrote in seeking the restraining order, according to the newspaper. Information on whether Stephen has retained legal counsel was not immediately available.

Following the crash, a neighbor told police they heard screams, NBC 7 San Diego reported. "Numerous neighbors reported a traffic accident, a vehicle driving into a house," San Diego Police officer Paige Foster told the outlet. "When officers got there, they found a woman who was deceased inside the home." As of Tuesday, December 30, police said they had not spoken with Stephen, who was intubated at UC San Diego Health, according to NBC 7 San Diego. Monica's restraining order against Stephen went into effect on December 1, the outlet reported. "In this case, unfortunately, the restraining order didn't protect her," San Diego homicide Lieutenant Chris Tivanian told NBC 7 San Diego. In court documents supporting her request for a restraining order, Monica detailed her husband's alleged paranoia and wrote that he "perceives me as someone he needs to protect himself from," according to The San Diego Union-Tribune. Bang Duong, who said he lived near the Coates, spoke with KGTV, saying he has known the couple since 2017. He mentioned that Stephen had experienced recent mental health issues.

Monica has two adult sons, ages 25 and 27, according to a GoFundMe established to support their mother's funeral and memorial expenses as well as other costs associated with her death.
