Wednesday marks one year since Leslie Merritt Jr. was released from jail.
Jason Lamm, attorney for Merritt, said the freeway shooting suspect volunteered to take a polygraph test to prove that he is not the correct suspect.
A polygraph test, provided by Lamm, showed that Merritt was truthful when he told the polygrapher that he is not the Interstate 10 freeway shooter.
The test was administered to Merritt on April 11, 2017.
Even though Merritt has been released from jail, the Arizona Department of Public Safety still believes Merritt is the suspect.
ABC15 has reached out to DPS for a statement.
