The Pennsylvania woman accused of stabbing two sisters, killing one and critically wounding the other, turned herself in and has been charged with murder, the Philadelphia Police Department announced Thursday.

The department told Fox News that Tiana Thomas, 19, who was wanted in connection with the Aug. 19 attack, surrendered herself to Philadelphia homicide detectives Friday evening.

Investigators said Thomas stabbed 23-year old Shawntae Garrison multiple times in the chest, back and legs during a clash investigators believe started as a neighborhood dispute.

Garrison was rushed to a nearby hospital and was pronounced dead about half an hour later.

Thomas also allegedly stabbed Garrison’s 28-year-old sister, who police said “sustained lacerations to her lip, forehead and wrist.”

The sister, whom police did not name, was transported to the same hospital and was listed in critical condition. Her current condition was not immediately known.
