What to Know

  • Groups of women got into an argument in Philadelphia's Brewerytown neighborhood late Monday.
  • A 23-year-old woman was stabbed to death, while her 28-year-old sister was injured, police said.
  • Tianna Thomas, 19, is charged with murder and remained at large Thursday.

A teenager accused of stabbing two sisters during a late-night street brawl in Philadelphia's Brewerytown earlier this week has been charged with murder.

Philadelphia police say 19-year-old Tianna Thomas remains at large, along with seven women who allegedly took part in the confrontation that broke out around 11:30 p.m. Monday at 29th and Jefferson streets.

Surveillance video captured a group of women getting out of a car and meeting up with others before they confront another smaller group of women, police said at a Thursday news conference.

Authorities say Thomas repeatedly stabbed 23-year-old Shawntae Garrison and 28-year-old Tayshawn Layton. Garrison died a short time later, while Layton remained hospitalized Thursday in critical condition.

A motive for the stabbings remains under investigation. Authorities say Thomas lived across the street from the sisters.
