PHILADELPHIA (KYW Newsradio) — The woman Philadelphia police say stabbed one sister to death and critically wounded another in Brewerytown is now in jail awaiting her next court day.

Tianna Thomas turned herself in last week to police just a day after they held a news conference naming her as their primary suspect, urging her to turn herself in.

Authorities say on Aug. 19, women from two rival groups met up in Brewerytown and a fight broke out. A video shows a woman police believe to be Thomas repeatedly stabbing 23-year-old Shawntae Garrison. Garrison later died at Jefferson University Hospital from her injuries.

Garrison's 28-year-old sister was critically wounded.  

The 19-year-old is set to face a judge for her preliminary hearing next month on murder and attempted murder charges.
