INDIANAPOLIS -- The suspected drunken driver accused of hitting and killing Indianapolis Colts linebacker Edwin Jackson has been living in the country illegally and did not have a driver's license, the Indiana State Police announced Monday.

The driver of the truck that killed Jackson and ride-sharing operator Jeffrey Monroe had been using the alias Alex Cabrera Gonsales, the police said in a release. Gonsales' given name is Manuel Orrego-Savala, and he is a citizen of Guatemala. Orrego-Savala had been deported in 2007 and 2009.

Monroe and Jackson were stopped on the side of Interstate 70 in Indianapolis when they were hit early Sunday morning.

Orrego-Savala, 37, was arrested after trying to flee the scene on foot, according to the Indiana State Police. Orrego-Savala was intoxicated, according to police. He is being held in the Marion County (Indiana) jail while the police work with U.S. federal immigration officials. Investigators are also working with the prosecutor's office to file criminal charges.

A probable cause affidavit filed Sunday in Marion Superior Court states that a breath test administered at the scene found Orrego-Savala's blood-alcohol content was 0.239 percent. Indiana's legal limit is 0.08 percent. Two vials of blood were later drawn from Orrego-Savala for testing.

Jackson and Monroe, of Avon, Indiana, were on the side of the interstate when Monroe got out of the car to help Jackson, who was sick. Orrego-Savala, who was driving a Ford F-150 truck, drove onto the emergency shoulder and hit the rear of the car, striking both Jackson and Monroe, with one of the bodies landing in the center lane of I-70, according to the police.

State trooper Ty Mays, who was in the area, reported to the scene after seeing the accident on the side of the road. In the process of slowing down, he hit the body of the victim who was in the center lane.

Monroe and Jackson were pronounced dead at the scene by the Marion County Coroner's Office. Monroe was 54; Jackson was 26.

"We were heartbroken to hear the news of Edwin Jackson's passing," the Colts said in a statement. "Edwin was loved by all in the Colts organization. We admired his outgoing personality, competitive spirit and hard-working mentality. He was well-respected among all with whom he crossed paths, and he will be greatly missed in our locker room and throughout our entire organization.

"We also understand that another person lost his life in the accident, only adding to our sorrow on this day. We are shocked and saddened by this tragedy, and our thoughts and prayers are with the families of both men during this difficult time."
