Man, 28, fatally stabbed by co-worker at Philadelphia International Airport

A dispute Thursday among airplane cleaners over a light's being turned off in a break room at Philadelphia International Airport ended with one man stabbed to death and another in custody, police said.

Lt. John Walker of Southwest Detectives said the incident involved three Worldwide Flight Services employees under contract to Frontier Airlines.

He said the dispute started about 11:30 a.m., when one man turned off a light in the employee break room in Terminal E and a coworker began arguing with him. The break room was not accessible to passengers. According to Walker, the argument turned into a scuffle, and when it subsided, a third man, age 35, pulled out a knife and slashed one of the other men in the stomach. Walker said some workers at the airport have access to knives or other sharp objects as part of their job responsibilities, which can include opening boxes.

The 28-year-old stabbing victim was taken to Penn Presbyterian Medical Center, where he was pronounced dead at 11:51 a.m., Walker said. He was identified Friday morning as Aaron Jenkins of the 100 block of West Roselyn Street in the city's Olney section.

Authorities at the airport took the 35-year-old into custody while he was waiting for a ride, Walker said. The man was being questioned Thursday afternoon at the Homicide Unit.

Police have not yet identified the suspect or announced charges against him.

The stabbing was "an unfortunate situation where people allowed their anger and aggression to get the best of them," but caused no major disruptions to airport service, Walker said.

Airport CEO Chellie Cameron issued a statement that said the airport was cooperating with police in their investigation of the "tragic incident."

"Our thoughts are with the family of the deceased," the statement said. "The safety of everyone in our airport community is our top priority. No passengers were involved or harmed in the incident and no flights have been affected."

Officials at Worldwide Flight Services' North American executive offices in New York did not immediately respond to a call and an email seeking comment.

Richard Oliver III, a spokesman for Frontier, issued a statement saying: "We've been made aware of an incident involving employees of Worldwide Flight Services (WFS)  at Philadelphia International Airport. The Frontier Airlines family is saddened to learn about this event and our hearts go out to those touched by the tragedy. We have reached out to WFS to assist them in any way possible as they deal with this incident."
