CHICAGO (CBS) — A 20-year-old man has been ordered held without bond, charged with strangling a Mount Greenwood teenager in May. Eighteen-year-old nursing student Karalynn McNicholas was found dead around 7 a.m. on May 11 near 60th and Maplewood, less than 12 hours after she went missing.

She was reported missing the night before, after she was last seen leaving her home near 111th and Central Park around 8:30 p.m.

An autopsy later determined she had been strangled, and her death was ruled a homicide.

Wednesday morning, police said 20-year-old Trevon Clark had been charged with first-degree murder in McNicholas’ death. Detectives determined he was the last person seen with McNicholas, and he was still in possession of her car – a 2014 Kia Sorento – when he was arrested.

Clark, who lives about a mile away from where McNicholas was found dead, was due to return to court on Sept. 10.

Police have not said how or if Clark and McNicholas knew each other.
