An Atlanta Falcons player is accused of killing his ex-girlfriend’s dog, Gwinnett County police said Friday afternoon. Within two hours, Prince Shembo was released from the team. Friday night, he turned himself in to authorities. Shembo, 23, has been charged with aggravated cruelty to animals, a felony, Cpl. Michele Pihera said. The Falcons responded to the allegations swiftly, releasing an emailed statement. “We are aware of the charges that have been filed against Prince Shembo,” the team said. “We are extremely disappointed that one of our players is involved in something like this. Accordingly, we have decided to waive Prince Shembo.” Prince Shembo (Gwinnett County Sheriff’s Office) Denicia Williams called police April 19 to report that her former boyfriend had killed her Yorkie, named Dior.

At some point during her stay, Williams left Shembo and her dog unattended. When she returned, Dior was unresponsive, she told police. Williams took the dog to Duluth Animal Hospital, where Dior died shortly after her arrival.

Although he was never charged, Shembo was investigated for allegedly sexually assaulting a Saint Mary’s College freshman in his dorm room in 2010. The 19-year-old woman, Lizzy Seeberg, killed herself 10 days later by taking an overdose of the antidepressant Effexor. “Pretty much it was an unfortunate event,” Shembo told reporters after being drafted. “My name was pretty much cleared. It’s behind me now. I just want to focus on playing football for the Atlanta Falcons.” In this July 25, 2014, file photo, Atlanta Falcons linebacker Prince Shembo runs drills during training camp.
