The man accused of killing Indianapolis Colts linebacker Edwin Jackson and another man is a Guatemalan immigrant who was in the country illegally and using an alias, according to police.

Manuel Orrego-Savala told police his name was Alex Cabrera Gonsales when he was arrested Sunday morning after allegedly ramming a black Ford F-150 pickup truck onto the emergency shoulder of an Indianapolis highway, killing Jackson and Jeffrey Monroe, a 54-year-old from Avon.

The 37-year-old, who was born in Guatemala, was driving without a driver's license and attempted to flee the scene of the accident on foot, according to Marion County Police.

Orrego-Savala had a blood-alcohol level of at least .15, which is nearly twice the legal limit, police said. He had previously been deported from the United States on two occasions, in 2007 and again in 2009.

Federal Immigration officials have placed a hold on him, and he is currently being held in the Marion County Jail. When he was arrested he told police he was a Mexican immigrant.

Jeffrey Monroe (pictured above) has been identified as the second man who was killed in the suspected drunken driving crash

State police identified the victims as Jackson, who grew up in Atlanta, and 54-year-old Jeffrey Monroe, of Avon, Indiana. Police say they were killed when a suspected drunken driver struck them as they stood outside their car along Interstate 70 on Indianapolis' west side

Authorities say the driver - identified as 37-year-old Alex Cabrera Gonsales of Indianapolis - struck them before dawn on Sunday and tried to flee on foot but was quickly captured. Toxicology results are pending

Indiana State representative Todd Rokita tweeted about the incident Monday, saying it should 'make all Americans angry.'

'A twice-deported illegal immigrant is suspected of killing 2 Hoosiers, including Colts LB Edwin Jackson,' he wrote.

'We must do more to get these dangerous illegal immigrant criminals off our streets, build a wall & put an end to illegal immigration.'

'It is believed Gonsales was intoxicated and was driving without a license,' Indiana State Police Sargent John Perrine said in a statement Sunday. The statement was released before police knew his real name.

Sunday morning's accident happened around 4am on Interstate 70, as Jackson and Monroe were standing outside a ride-share car. It is believed that Monroe was a ride-share driver who was assisting Jackson, who had become ill, investigators told the Indy Star.

The Colts said in a statement Sunday that the team is 'heartbroken' by Jackson's death. The statement says the 26-year-old 'was loved by all in the Colts organization.'

'One of the people struck was thrown into the center lane of I-70,' Perrine said in the statement.

'Shortly after the crash, and before any 911 calls were received, Trooper Ty Mays was driving through the area and noticed a vehicle in front of him make an evasive maneuver to the left.'

Mays spotted the crash on the right side of the road before activating his emergency lights, Perrine said.

'As he slowed to stop for the crash he struck the body of the victim in the center lane,' Perrine said in a statement. It is not known which victim was struck by Mays.

The Colts Twitter account posted a picture of smiling Jackson. He was 26-years old

Colts owner Jim Irsay responded to the news on Twitter.

'Our hearts and prayers are with Edwin Jackson's family,' he wrote. 'Terrific young man, respected and liked by all. Rest In Peace, Edwin.'

The team's Twitter account also posted a smiling picture of Jackson.

'It is with a heavy heart that we share the loss of one of our own,' read the Colts Twitter account post. 'Edwin Jackson always brought a smile to our locker room and the community. Our thoughts are with his family and friends during this difficult time. We will miss him greatly.'

An inside linebacker, Jackson signed with the Colts in 2015, but didn't dress for a game until the following season, when he appeared in all 16 games, half of which he started.

That season Jackson was the team's third-leading tackler, but he suffered a season-ending injury during the 2017 preseason so he spent the year rehabilitating.

Jackson had an inauspicious start, first walking on at at Georgia Southern, where he ultimately led the team in tackles by his senior season. He was also part of Georgia Southern's infamous upset of Florida in 2013.

Jackson was also a state-championship-finalist wrestler from Atlanta when he was in high school.
