GRAND RAPIDS (WWJ/AP) - A western Michigan man has been sentenced to life in prison without parole for killing a 16-year-old girl while free on bond, preventing her from testifying that he'd raped her.

Quinn Anthony James, 43, of Wyoming, Michigan, learned his sentence Monday after a Grand Rapids jury found him guilty of first-degree murder in the strangulation death of Mujey Dumbuya.

The teen was reported missing on January 25, 2018, after she left for the bus a day earlier and didn’t show up at East Kentwood High School.

Dumbuya's partially clothed body was found four days later, about 50 miles southeast of her Grand Rapids-area home, by two people out for a walk in the woods. Her cause of death was listed as "asphyxia, including strangulation" on the death certificate.

James was a maintenance worker at Dumbuya's school, and she accused him of sexual assault in 2017.

Authorities said James killed the girl while he was out on a $100,000 cash bond in the assault case.

Kent County Prosecutor Chris Becker told The Associated Press that the bond appeared appropriate to him at the time, given the charge. "$100,000 is not an insignificant amount — it was a substantial cash bond that (Kentwood District Judge William) Kelly put out," Becker said. "He posted bond — it happens."

James was sentenced last December to 20 to 30 years in prison for third-degree criminal sexual conduct for assaulting the teen.

On a "Justice for Mujey" Facebook page, family members noted that while James received the maximum sentence for his crimes, nothing can bring the teen back. Replying to numerous comments offering words of support, a person running the page wrote: "Sometimes words can't express the depth of our hurt. Indeed, only God can give that peace. Thank you so much for your thoughts and prayers. Stay blessed."
