The death of a Texas airport worker who was sucked into a jet engine Friday night has been ruled a suicide, officials said Monday.

The worker, identified Monday as 27-year-old David Renner, died of blunt and sharp force injuries at San Antonio International Airport, KEN 5 reported, citing the ruling from the Bexar County Medical Examiner Office.

The medical examiner’s office said staff “saw signs that pointed to suicide,” according to WOAI.

Emergency crews discovered the horrific scene after responding to reports of a ground worker that was “ingested” into the engine of the Delta plane that had just landed from Los Angeles.

An investigation was initially launched by the National Transportation Safety Board, but came to a halt Monday after the medical examiner’s determination.

“The NTSB will not be opening an investigation into this event. There were no operational safety issues with either the airplane or the airport,” an NTSB spokesperson said, according to KEN 5.

Both Delta and the company that hired Renner, Unifi Aviation, previously expressed condolences over the sudden death.
