Police say Hedglin climbed over razor wire fence to break into a Delta Airlines regional plane operated by SkyWest around midnight at the St. George Municipal Airport in Utah. After starting up the plane, he allegedly drove the plane into a fence and a parking lot.

"There were no passengers onboard the CRJ200 as it was not in service at the time," SkyWest released in a statement. "The aircraft did sustain damage; the extent of the damage is currently being inspected by our maintenance and safety professionals."

After failing to get the plane airborne, he took his own life.Investigators don't know why he was at the Airport or what his plans were.

"We may never know that," Capt. James Van Fleet, with the St. George Police Department, said. "The person that has those answers is dead unfortunately, so we can't talk to him. We're trying our hardest to figure out some the answers to these questions."

According to SkyWest, he was listed as a "current/active" employee. However, once he was being investigated in the homicide case, they put him on leave.

Hedglin had been a licensed pilot since 1998. He was certified as an Airline Transport Pilot and rated to fly regional jets.SkyWest confirmed he was employed as a pilot for them.

Hedglin was a wanted fugitive, suspected of killing his former girlfriend, 39-year-old Christina Cornejo,in Colorado Springs.

Colorado Springs Police say they were sent to the 1000 block of Cheyenne Villas Point on Friday to conduct a welfare check on Cornejo. When they arrived, police found her stabbed to death.

A troubled relationship

According to court papers, Cornejo and Hedglin dated for about four years, until she said she wanted a break in March. He followed her home the night of the breakup, stormed into her apartment, took some of her belongings he gave to her and smashed her computer.

"When I read this report, the thing that stuck out to me was how jealous he was," said Janet Kerr, Interim Executive Director of TESSA, a domestic violence organization in the Springs. "She wanted to end the relationship or take a break in the relationship, and that was the point where he said 'uh' and went nuts."

Kerr says domestic violence isn't always physical.

"What's behind all of that is an attempt to intimidate," Kerr said. "It's also a sign there is anger control and impulse control issues, and we know that's typical of offenders of domestic violence. When they feel that person is going to leave, it just scares them to death, really underneath the rage, the anger, the jealousy, is fear."

Cornejotold police he did not hurt her, but did intimidate her. Police arrested Hedglin on suspicion of criminal mischief, theft and harassment.

Unanswered Questions

Hedglin was free on a $10,000 bond from that harassment case awaiting trial in August when Cornejo was killed. Police still need to wrap up their murder investigation, and have critical unanswered questions: Was she abducted? Did she go willingly? Why was the murder committed, and what brought Hedglin to Utah.

The only two people who know that information are both dead.

Police knew Hedglin was a pilot with SkyWest, "so we called SkyWest and ask them to deactivate his access cards in the event that he showed up there," Barbara Miller said. Sky west complied and his privileges were revoked.

Police are still investigating both incidents.

"A lot of people are under the misconception that once the suspect is dead that the investigation is closed automatically," Miller said. "That's not the case. Our investigator still have a lot of work to do."

According to the Colorado Army National Guard, Hedglin was a part-time soldier with their organization. The Guard told 9NEWS he was a food service specialist with no other specialized military training and had never been deployed.

Cornejo was a 2nd lieutenant with the Colorado Army National Guard's 100th Missile Defense Brigade in the Springs. The Commander of the unit released a statement on Tuesday night that said, in part, "I'm always saddened by the loss of a Guard member. The tragic nature of this only worsens the blow. Christina was not only a stellar soldier, but a fantastic young leader who set high standards."
