T.J. Lane, the 17-year-old accused of killing three teens and injuring two in a shooting at an Ohio high school may have files charged against him today. According to CNN, a judge ordered charges to be filed by Thursday.

The teen, who confessed that he took a .22-caliber gun and knife to school on Monday, is said to be facing three counts of aggravated murder among other charges. According to ABC News, prosecutors say that Lane will be tried as an adult.

Geauga County Prosecutor David Joyce told ABC News that the teen confessed to taking the pistol and admitted he went into the cafeteria and shot 10 rounds. During his shooting spree Lane had shot a total of five people, only two of them surviving.

Aggravated murder is murder in the first degree. According to the Cleveland Ohio Law Library Association, a person who commits such a crime can be sentenced to the death penalty, life in prison without parole, or life with parole starting after 20 years. Ohio law 2929.02 murder penalties state that Whoever is convicted of or pleads guilty to aggravated murder in violation of section 2903.01 (aggravated murder ) of the Revised Code shall suffer death or be imprisoned for life. The law also states that no person under the age of 18 at the time of the offense shall face death. Lane's sentencing will reflect on whether prosecutors will go through with trying the 17-year-old as an adult.
