EL RENO -- Prosecutors said today that murder defendant Joshua Steven Durcho murdered his girlfriend because she had threatened to call the police on him.
Durcho, 26, had vowed he would never go back to prison, prosecutors said.
Prosecutors made the allegations in a 14-page court filing that outlined the reasons they say he deserves the death penalty if he is convicted.
Durcho was arraigned today on five counts of first-degree murder in the Jan. 13 deaths of Summer Rust, 24, and her four children, Kirsten Rust, 7, Autumn Rust, 7, Teagin Rust, 4, and Evynn Garas, 3.
Prosecutors also said they have evidence Durcho sexually violated the bodies of the two 7-year-old girls, possibly after their deaths.
After the family was killed in their El Reno apartment, Durcho fled to Texas. He visited family members and friends in an effort to sell tools to finance his flight.
"And he expressed no remorse for his conduct," prosecutors said in the court filing.
At an arraignment this afternoon, Judge Edward Cunningham entered not guilty pleas for Durcho.
The trial was scheduled for April 5.
