(FOWLER, IN) - 57-year-old Steven Farrell is still being sought by police for the murder of his girlfriend, 40-year-old Christine Craig on Friday.
Farrell's truck was found in a parking lot at the Indianapolis International Airport on Sunday after a tip to authorities.
Police won't be able to look at surveillance footage until later Monday because of the holiday weekend.
Police say Craig had pulled her car up to Farrell's truck, got out, and exchanged words with him.
She then got into the passenger side of her car when Farrell allegedly shot her.
Craig's 16-year-old daughter drove her to a gas station in Otterbein, where she died from her injuries.
Farrell is described as five-feet-seven-inches tall, 200 pounds with salt and pepper hair and brown eyes.
He is considered possibly armed with a handgun.
