A woman whose body was found this week in her home was beaten to death, and investigators seized computer equipment found in the house, police said Friday.
Police are also looking into information written in an anonymous letter given to local media outlets about the death of Julie Mitchell, 34.
Mitchell was found late Tuesday in her Oklahoma City home near Edmond in what was first reported as a suicide by one of her stepsons. Police later determined her death was a homicide.
Mitchell's 13-month-old daughter was placed with a family member after the body was found about 10:20 p.m. Tuesday at the house at 640 NW 150.
Mitchell suffered multiple blunt force trauma wounds to the head, said Cherokee Ballard, spokeswoman for the medical examiner's office. There was no indication of sexual assault, authorities said.
A police spokeswoman said no one has been ruled out as a suspect.
Oklahoma City police Sgt. Jennifer Wardlow said police seized computer equipment from the home and will examine it for any possible clues about Mitchell's death.
Police asked that details of the letter provided to the media not be released.
"The letter had things they (detectives) were already aware of, but some of it had things that our investigators will check out," Wardlow said.
Mitchell's husband, Teddy Mitchell, 56, was out of town at the time of her death, one of his sons said.
Police said Teddy Mitchell is known to be involved in illegal gambling, and his online profile on an Internet gambling site mentions poker tournaments in which he competed.
Police have learned Teddy Mitchell is a bookie, someone who illegally collects bets on sporting events, authorities told The Oklahoman.
