Authorities are searching for two Phoenix brother who were reported missing nearly a week ago. However, this isn't the first time the boys have been reported missing.
According the National Center for Missing & Exploited Children, 16-year-old Christian Tackett and 17-year-old Josiah Stevens were last seen on March 21.
They were last seen in the area of 11th and Van Buren streets, a police spokesperson said.
The boys, who ABC15 previously reported have autism, were also reported missing last November. They were returned home after being recognized at a Phoenix sandwich shop.
February 2016, Stevens was reunited with family after being reported missing. At the time, police were concerned because the family had just moved to the area and worried that he couldn't find his way home from the school bus stop.
At the time of their disappearance, Christian was wearing a gray T-shirt, with the words "Gone Wild" on it and jeans with a hole on the left side. He is described as having brown hair with blonde patches. He's about 5'11" and 138 pounds.
Josiah was last seen wearing a black T-shirt with neon writing, jeans and black shoes. He has a scar on the side of his head and a crooked left front tooth. He's 5'6", 112 pounds with blue eyes.
Anyone with information about the pair's whereabouts is urged to call Phoenix police.
