CHICAGO (CBS) — It was a Facebook fight that turned deadly.

CBS 2’s Brad Edwards reports, a Chicago woman is in custody–captured out of state–after a battle in social media spun out of control and led to a fatal shooting.

Khalila Southall, 30, who fled to Rochester, Minn., following the Aug. 26 shooting, allegedly admitted to Chicago Police that she and Lakeisha Tate had an argument on the social media site

Before she was killed, Tate, 28, made a purchase and was walking out of the Citgo gas station in the 3300 block of West Harrison when she was confronted by Southall.

The two tussled, and Southall pulled out a gun and shot Tate, prosecutors said.

Tate later died at Stroger Hospital.

Southall left her ID card at the scene, and surveillance footage captured her attacking Tate.

Earlier this month, Southall was arrested in a domestic incident in Rochester.

When she allegedly gave an officer a fake name, authorities grew suspicious and soon discovered there was a warrant for her arrest in Chicago.

Southall is being held without bond.
