He admitted to the Chardon High School shootings and made some vulgar remarks in the process.
Now TJ Lane is fighting his conviction.
Lawyers for the 18-year-old filed an appeal with the 11th District Court of Appeals, on his behalf.
On Feb. 27, 2012, Lane entered the cafeteria at Chardon High School and opened fire.
17-year old Russell King, Jr., 16-year-old Daniel Parmertor and 16-year-old Demetrius Hewlin were killed in the shooting. 17-year-old Nick Walczak remains paralyzed from the waist down. 18-year-old Joy Rickers and a 6th, unidentified victim were treated and released from the hospital.
Lane was convicted and sentenced to life in prison last month.
He is currently locked up at the Lorain Correctional Institution.
