A Knoxville man has been charged in connection with the fatal shooting of his girlfriend — one of three shootings reported across the city Sunday.

Knoxville Police Department officers responded at 1:45 a.m. to a report of a deceased person inside a home at 4100 Deer Run Drive in Northwest Knoxville. The victim was identified as Sherril Johnson, dead of an apparent gunshot wound, according to an arrest warrant.

Timothy Dion Wells, 44, initially told authorities Johnson "for some unknown reason shot herself in the head," the warrant states.

After being advised of his Miranda rights, Wells later admitted to investigators he had shot his girlfriend and then lied about it, the warrant reads.

Wells now is set for arraignment April 9 on a charge of second-degree murder. He was released from jail on bond late Sunday night.

The incident was the first of three shootings KPD responded to Sunday.

One person was killed and two others were wounded in a shooting reported shortly after 4 a.m. near The Vibe nightclub, 2630 N. Broadway.No arrest has been announced.

Knoxville police also are investigating a shooting with at least one victim reported at 7:36 p.m. on the 1900 block of Linden Avenue. No other details were immediately available Monday morning.
