LAWRENCE, Kan. (AP) — A man has been charged with first-degree murder and aggravated burglary in connection with the death of a woman who lived two doors down from him at a Lawrence apartment complex.

The Lawrence Journal-World reports 18-year-old Rontarus Washington Jr. was arrested in January in Mississippi and was returned to Lawrence. He was booked into Douglas County Jail early Monday morning.

He made his first appearance via video in Douglas County District Court on Monday afternoon. He denied that he was involved in the death of 19-year-old Justina Altamirano Mosso, whose body was found in November in her apartment.

A judge set his bond at $750,000. His next court appearance is set for March 23.

It wasn’t immediately known if Washington has an attorney.
