PHOENIX -- A staffer at St. Luke's Behavior Health Center is accused of sexually assaulting a 14-year-old patient.

On the night of Feb. 28, investigators believe 27-year-old Eddie Parker entered the room of the girl and started kissing her.

According to the police report, Parker left and entered the room three other times, each time escalating the level of molestation until ultimately, he had his hand down the girl's pants.

"I think this is a case where an individual has taken a position here to get closer and closer to this person while they were there," said Sgt. Trent Crump.

Parker didn't know the victim before she was admitted, but reportedly got closer to her over time. His alleged advances were not welcome, and the young victim reported the assault to police the very same night.

"The child came forward to other health care workers and felt comfortable to come forward," said Crump.

Parker's neighbors said he was polite and quiet and never gave any indication that he was capable of such a crime.

"He lived right next door and I didn't know. I'm glad he's gone because I don't want someone like that living next to me knowing I have children and he could be doing something like that," said Felicia Morales.

All employees of St. Luke's go through stringent background checks. Parker's showed no criminal history.

St. Luke's Behavioral Health Center CEO Greg Jahn released a statement late Tuesday night stating, "At St. Luke's Behavioral Health Center, patient safety is our top priority. Upon the report of a patient allegation, we took immediate and appropriate action. We would like to express our concern for this patient and to offer our assurance that we are working closely with law enforcement to ensure justice."

Parker faces six felony counts, including sexual abuse, molestation of a child and sexual conduct with a child. Because he is a health care worker, he could face stiffer punishment.

He is currently being held without bond at a Maricopa County jail facility.
