SANTA ANA, Calif. -- An Arizona woman who was arrested on suspicion of killing her son and daughter and then crashing her car into an electrical box in an apparent suicide attempt had a propane tank in her vehicle and tried to choke herself with a rope or belt as rescuers approached, a police spokesman said Sunday.
Santa Ana police Cpl. Anthony Bertagna identified the mother Sunday as 42-year-old Marilyn Edge of Scottsdale, Ariz.
The children's names were not released.
Edge was booked late Saturday on two counts of murder.
The woman, who crashed her car Saturday outside a Home Depot in Costa Mesa, told officers they could find her children in a hotel in the nearby city of Santa Ana, Bertagna said.
It was not clear why Edge, whose car has a Georgia license plate, was in Orange County or what links she had to the area.
Police obtained a search warrant late Saturday for the hotel room where the children were found.
"Last night, it was mainly trying to figure out who these people were and dealing with the scene itself," Bertagna said.
Police in nearby Costa Mesa were called to a parking lot Saturday where Edge had crashed her gray Honda Accord into protective poles surrounding an electrical box, Costa Mesa police Sgt. Tim Starn said.
"It was clear that it was an intentional act," he said.
Officers then found the children dead in a third-floor room at the Hampton Inn & Suites in Santa Ana.
No weapon had been recovered from the scene, Bertagna said.
Hotel guests were stunned at the discovery at the quiet inn on a sunny weekend in Southern California.
"My goodness, if there's two children involved that's just horrendous, to say the least," Mike Ramey, who was staying at the hotel with his fiance, told KABC-TV. "As a parent, it's just a heartbreaker."
