The Shelby County District Attorney's Office says Demarion Tackett will be charged as an adult, reported WHBQ-TV. The station learned during a June 13 court hearing that the teenager faces at least 19 charges in connection with the murder.
Police said Materna had been selling his watermelons in Memphis for decades.
According to authorities, Materna, known by many as “Red” or the Watermelon Man, was robbed by two men who were seen getting out a silver Infiniti that had a paper tag reading “RETIRED” on it.
Materna’s longtime friend Randall Linn talked to WREG, saying Materna also had a gun, “He (Red) shot back. Don’t know if he hit anybody going down or the car, but I know he was protecting himself as well as the other neighbor.”
On May 29, Materna died after he was taken off life support, officials said.
