MONUMENT, Colo. (AP) — Colorado authorities say a couple who had custody of a girl whose body was found in a vacant home have been arrested in Nevada.

El Paso County Sheriff's Lt. Lari Sevene said Wednesday that Hanif Sims and his girlfriend, Monique Lynch, were in custody in Henderson, Nev. She said investigators had just learned of their arrest and had few details.

Sims is the father of 9-year-old Genesis Sims, whose body was found May 14 in the crawl space of a vacant town house in Monument, about 50 miles south of Denver.

Authorities say Genesis had lived in the town house with Sims and Lynch.

Investigators had been looking for the couple, who moved out of the home early last year.
