The boyfriend of Millserville University freshman Karlie Hall, 18, was arrested for criminal homicide on Monday after admitting he had shoved her and hit her in the face.

Gregorio Orrostieta, 19, told police that early on Sunday he had pushed her, which caused her to fall and hit her head, reports the Associated Press. He then said he gave Hall a “back-hand,” which knocked her out. When officers arrived to Hall’s dorm room, which was where the incident took place, Orrostieta was performing CPR on her. However, authorities believe the CPR “was completely fake,” reports Fox 43.

The affidavit says the boyfriend had blood on his face, hands and jeans as well as cuts and scratches on his face and chest. Orrostieta is not a Millersville University student.

An autopsy done on the victim indicates she was beaten and strangled, and that she had been dead for several hours before the suspect called police, reports Reuters.

An earlier statement released prior to the autopsy from the Lancaster District Attorney’s Office provides additional details on the incident:

At approximately 5 a.m. on Sunday, February 8, 2015, members of the Millersville University and Millersville Borough police responded to a call at Bard Hall on the Millersville University Campus for a cardiac arrest. Upon arrival, officers found an unresponsive, female student in her dorm room.  Millersville University and Millersville Borough Police, in conjunction with the Lancaster County Forensics Team and Lancaster County District Attorney’s Office began an investigation into the student’s death.  The student has been identified as Karlie Hall (DOB: 10-3-1996), a freshman from Chadd’s Ford, PA.  Ms. Hall’s death is under suspicious circumstances. The exact cause of death is not immediately apparent so law enforcement officers will await additional information from the autopsy before further actions are taken.  An autopsy is scheduled for tomorrow morning.

Karlie’s boyfriend, Gregorio Orrostieta (DOB:6-3-1995) of Kennett Square, PA, has been charged with Aggravated Assault as a result of the investigation showing there was a physical altercation between the two in the early morning hours.  More information will be provided tomorrow afternoon after the autopsy is conducted. Mr. Orrostieta is in custody at Lancaster County Prison.  There is no evidence that anyone else is involved and law enforcement officers are confident that there is no danger to the campus community.

The university is providing counseling services for students personally impacted by the tragedy.
