Police say a mother and daughter were found slain at an Irving home after a man walked into the police department Sunday night and admitted to the killings.
Irving police said Tyrone Cade, a 38-year-old registered sex offender, told officers he had killed two people at his home in the 1400 block of Ronne Drive.
The latest news from around North Texas.
Officers went to the residence and found the bodies of Mischell Fuller, 37; and her daughter, Desaree Hoskins, 18, both of Irving.
Investigators said Cade admitted to stabbing Fuller, his live-in girlfriend, after he heard her talking with her former husband on a recording from a device Cade left under the bed.
Police said Hoskins was stabbed while trying to save her mother.
Irving police said Cade considered suicide and even left he note. More than 16 hours after he killed Fuller and Hoskins, he turned himself in, police said.
Police say Cade confessed in police lobby
Investigators said Cade walked into the front lobby of the Irving Police Department at about 8:30 p.m. and called 911.
"When he came in here -- at that late at night, there's not anyone here," Officer John Argumaniz said. "So what he did was, he used his phone, and then he called and he said, 'Hey, I want to talk to an officer about what took place, so they sent an officer here to talk to him."
Police said it appeared Cade, Fuller and Hoskins all lived at the residence.
Cade has been charged with one count of capital murder.
Friends mourn mother, daughter
A makeshift memorial is growing outside Cade's south Irving home.
"We didn't see this coming," said Norma Argueta, a friend of Fuller's. "We did not expect that anything like this would happen to her. We were looking forward to our children graduating high school, and she was moving on for the next chapter in her life."
Dozens of shaken students at Irving High School spoke with grief counselors Monday.
"[A] lot of people are suffering today because of her loss," said J. Pat Lamb of the Irving Independent School District. "It's a testament to her character. They liked her; she liked them."
Hoskins, who friends called Dee Dee, was about to graduate.
"Class of 2011 won't be the same without her," said Stephanie Delfin, a friend. "She was, she was part of us, and when we graduate, it's going to be for her. This is all for her now."
