Police rushed to a South Philadelphia hotel Thursday morning after a Philadelphia school teacher from Delaware County was found stabbed inside the women's restroom.
The women later died at the hospital and investigators believe her wounds were self inflicted.
Police cars could be seen outside the Holiday Inn on Packer Avenue shortly after the woman -- a 48-year-old from Newtown Square, Pennsylvania -- was found around 8:10 a.m.

Police said the woman suffered stab wounds to her throat, chest and arms. They found her inside a stall locked from the inside with a pair of scissors and a steak knife nearby.
Medics rushed her to the Hospital at the University of Pennsylvania in critical condition. She later died from her injuries, according to police.
The Philadelphia School District didn't name the victim but they did confirm that she worked as a sixth-grade teacher at Francis Scott Key School at 8th and Wolf in South Philly. She arrived for work Thursday to drop off some materials but left a short time later, according to the district.
Crime scene investigators remained on the scene for hours sorting through clues. They also interviewed her husband before determining that she likely slashed herself.
The Holiday Inn offered no comment outside of saying that they are cooperating with police. Police said hotel surveillance shows the victim entering the restroom at 7:46 a.m. A witness found her about 10 minutes later.
Grief counselors will be on hand at the school, according to police.
