CENTERVILLE, Ohio- Spirit Airlines pilot Brian Halye, 36, and wife Courtney, 34, were found dead Thursday in a bedroom of their home in Centerville, south of Dayton, police said.

The couple’s children can be heard on a 911 call after their parents failed to wake them for school, NBC reported.

“They were very cold,” their son told a dispatcher while his three sisters can be heard crying in the background.

The son added that they found their parents in bed not breathing and that his sisters described their father’s face as “pale and there was black lines all over his face.”

Spirit Airlines confirmed Friday of Halye’s appointment and said his final flight was March 10.

“Captain Halye served at the airline for just over nine years,” Spirit Airlines said in a statement, noting that they run random drug and alcohol tests on all employees.

The airlines said anyone who tests positive for drugs is immediately fired.

WHIO reports that in January of 2016, Nancy Casey, Courtney Halye’s mother, contacted Centerville police and said she felt her daughter threatened to harm herself and was abusing narcotics.

Casey told officers her daughter had been “hooked on drugs” on and off for about seven years. The mother suspected her daughter was high when talking with her that day, the report said.

In that same report, which covered events of Jan. 5-6, 2016, Brian Halye contacted police after he had returned from Detroit, where he worked for Spirit Airlines as a pilot. Brian Halye told officers he had called and texted his wife, who had hung up on him and would not tell him where she was.

Police used her cell phone to determine she was in east Dayton but did not immediately find her. When officers found her vehicle, Courtney Halye was not there.

Later on Jan. 6, 2016, Brian Halye told police his wife had returned to their house but had locked him out. He worried that she was trying to get to two unloaded guns he kept inside, so he forced entry.

Courtney Halye was holding both guns, the report said, and her husband took them from her just as officers arrived there, the WHIO report said.

Police said that she appeared mentally unstable and possibly intoxicated or having a medical issue related to diabetes. The officer requested medics, who took her to the hospital for treatment.

Brian Halye told officers that day his wife had battled heroin and cocaine addiction “for quite some time.”
