MILWAUKEE — The Milwaukee County medical examiner has positively identified a Medical College of Wisconsin resident found dead at Froedtert Hospital Tuesday as 43-year-old Wayne Hendrix.

The preliminary manner of death in this case has been ruled a suicide, the result of a lethal amount of self-administered fentanyl, according to the medical examiner’s report.

Hendrix was pronounced dead at Froedtert Hospital on Tuesday around 3:30 a.m.

According to a news release from the Milwaukee County Sheriff’s Department,deputies responded to a call from the medical complex after Hendrix allegedly pointed a gun at another employee. Police say Hendrix then entered an operating room and signed onto the computer to administer medication before injecting himself with fentanyl.

Sheriff’s SWAT team members, deputies and hospital security evacuated the area and searched for Hendrix. Officials said Hendrix did not respond to attempts to negotiate with him. He was later found dead after a camera placed under the door captured an image of Hendrix down on the floor with an IV in his arm.

Hendrix was a resident anesthesiologist at Froedtert.

A gun was recovered from the scene.
