An immigrant illegally living in the U.S. was charged with four felonies in the drunken driving crash that killed Indianapolis Colts linebacker Edwin Jackson, prosecutors announced in court Wednesday.

Manuel Orrego-Savala, 37, was wearing an orange jail suit during a Marion County (Indiana) court appearance. He was charged with two counts of causing death while operating a vehicle above the legal alcohol limit and two counts of failing to remain at the scene of an accident.

During his initial court hearing, Orrego-Savala responded through an interpreter as the judge explained the proceedings and charges.

"He's very distraught to say the least," said his lawyer, Jorge Torres. "He's very confused."

Court documents allege a blood test conducted at a hospital determined Orrego-Savala had a blood-alcohol level of 0.19 percent, more than double Indiana's legal limit for driving.

Orrego-Savala had been deported twice -- in 2007 and 2009 -- according to Indiana State Police. The driver, who had been using the alias Alex Cabrera Gonsales, is a citizen of Guatemala.

Orrego-Savala was driving the truck that struck and killed Jackson and ride-sharing operator Jeffrey Monroe in Sunday's crash along Interstate 70 in Indianapolis.

Orrego-Savala was arrested after trying to flee the scene on foot, according to police, who also said he was intoxicated. Orrego-Savala is being held in the Marion County jail, and police are working with U.S. federal immigration officials.

President Donald Trump took to Twitter on Tuesday morning and called the accident that claimed the life of Jackson "disgraceful."

"So disgraceful that a person illegally in our country killed @Colts linebacker Edwin Jackson. This is just one of many such preventable tragedies. We must get the Dems to get tough on the Border, and with illegal immigration, FAST!" Trump tweeted.

The crash happened shortly before 4 a.m. along I-70, according to the Indianapolis Star. Police said Jackson, 26, and Monroe, 54, were standing near a stopped vehicle when a pickup truck drove onto the highway shoulder and struck them both.

Police believe that Monroe was driving and had pulled to the side of the road and got out of the car to assist Jackson, who became ill. Monroe and Jackson were pronounced dead at the scene by the Marion County Coroner's Office.

Jackson previously played for the Arizona Cardinals. He was signed by the Colts in January 2016 after signing to the practice squad the previous month. Jackson was placed on injured reserve in September 2017.
