MARTINEZ -- A 21-year-old Concord man was sentenced Tuesday to 29 years and four months in prison for killing a female acquaintance after raping her in a Concord park in 2010.

Tirrell Lavell Dudley had been awaiting his murder trial in the death of 31-year-old Javaughna Lynch when he took a plea deal in May. He pleaded guilty to voluntary manslaughter, rape, sodomy, robbery and a weapon enhancement, deputy district attorney Jill Henderson said.

Lynch, who lived in Concord and Richmond, and Dudley had been drinking vodka and orange juice together in John Baldwin Park on July 12, 2010, when Dudley turned on Lynch.

After sexually assaulting Lynch, Dudley bashed her head in with a rock and strangled her with one of her shoelaces, Henderson said. He stole her pocket money and cellphone before leaving the scene.

The next morning, a passer-by found Lynch's body facedown and partially disrobed. The shoelace was still around her neck. Dudley was arrested that day but released for lack of evidence.

He was arrested again and charged with murder three months later after his DNA linked him to the sexual assault.

Dudley claimed that he had consensual sex with Lynch and killed her for no reason, but the physical evidence indicated he raped her, Henderson said.

At the time of his arrest, Dudley was a student in the Alliance program, a school for youths with emotional troubles.

Lynch was a student at the Loma Vista Adult Education Center and the mother of a boy who is now 10 and being raised by Lynch's mother.

Dudley's attorney could not be immediately reached for comment Wednesday.
