TAMPA - Tampa Police have arrested a second suspect in the death of a 16-month old child.

Tonya Myers was arrested Thursday and faces a charge of aggravated child neglect. She is the girlfriend of 23-year-old Dwayne Poole, who was charged with aggravated child abuse and first-degree murder.

Police say Poole beat his son, Ronderique Anderson, causing his death.

Investigators believe Myers knew Poole was abusing his son. When being interviewed about the young boy's swollen jaw and missing teeth, she told police she knew Poole had knocked out the child's teeth.

Police say Ronderique died as a result of the injuries last Friday.
