Police say a 35-year-old man stabbed his 28-year-old co-worker in the stomach inside Terminal E, which houses Frontier Airlines.
Police say a fight between three Worldwide Flight Services employees, who are contracted by Frontier Airlines to clean planes, led to the fatal stabbing.
The victim was transported to Presbyterian Hospital in critical condition and was later pronounced dead.
Authorities say the suspect ran away following the stabbing, but airport police were able to catch him and he is now in custody.
