Phoenix Teen Bit and Beat Girlfriend’s 3-year-old Girl To Death An 18-year-old Phoenix, AZ man is accused of beating his girlfriend’s 3-year-old daughter to death. According to reports by the NY Daily News: A Phoenix man brutally beat and bit his girlfriend’s 3-year-old daughter to death – and nearly did the same to her year-old sister, police said. Martwane Mackey admitted to authorities he assaulted both girls, but denies killing the elder one, the Arizona Republic reported Tuesday. The 18-year-old claims young Ty’Shea Austin suffered a “choking and respiratory incident” Saturday, while he was watching the girl and her little sister, Zariah, police said. His girlfriend, Qnique Thues, was at work at the time. The couple lived together. Mackey said he did not immediately call 911 or take the child to the hospital, but instead struck and bit the toddler to revive her, authorities said in a police report. Mackey eventually called 911 from a pay phone around 2 a.m. Saturday, police said. When cops arrived, they found him with the 3-year-old in his arms. “He’s a monster, and people need to know he’s a monster,” Rhonda Brown, Ty’Shea and Zariah’s grandmother, told ABC 15 News. “I don’t think death is good enough for him, I think he needs to be beaten like he beat her.” Mackey was arrested and charged with first-degree murder and child abuse.
