TACOMA, Wash. (AP) — A Tacoma man accused of killing a pregnant woman and discarding her body on a wooded cliff has been charged with first-degree murder.

Colin Dudley pleaded not guilty Friday in Pierce County Superior Court in connection with the slaying of Kassandra Cantrell of Parkland, KING-TV reported.

The judge ordered Dudley held on a $2 million bond. He was arrested at his home on Tuesday. Investigators said Cantrell’s wrapped body was also found that day

Cantrell, 33, disappeared Aug. 25 after she left her family’s house in Parkland. Her vehicle was found abandoned near the Tacoma Dome soon after.

An autopsy by the Pierce County Medical Examiner confirmed the identity of the remains to be Cantrell through dental records, according to court documents released Friday.

Cantrell discovered she was pregnant in July and told her doctors Dudley was the father, according to court documents. However, Dudley denied having any recent relationship with Cantrell to detectives, and said there was “no way” he was the father. He said they had dated several years ago.

Detectives obtained Cantrell and Dudley’s cellphone records, which confirmed Dudley did have contact with Cantrell repeatedly as far back as February of this year, documents said. They also communicated on the morning of Aug. 25, which is when Cantrell was last seen, according to court documents.
