On Thursday, U.S. Marshals in Mississippi arrested 27-year-old Randall Beaty on charges of first degree murder and aggravated abuse of a child under the age of eight.
Beaty was indicted earlier this month by a grand jury in Sumner County for the October 2010 death of 9-month-old Shayla Peveler.
The infant was admitted to Vanderbilt Children's Hospital on October 29, 2010 with severe injuries.
Shayla Peveler later died on October 31. Blunt force trauma was the cause of death, according to the medical examiner's office.
"We're the voice of the little 9-month-old little girl. She can't help herself, and no one else is helping her, so that's what we've got to do," Hendersonville Police Detective Jim Bachman said.
"This was a very detailed investigation that took quite a bit of time, and we wanted to make sure that we were correct when we did seek the indictment last week before the grand jury," Sumner County District Attorney Ray Whitley told Nashville's News 2.
On Friday, Beaty was transported back to Tennessee where he was booked into the Sumner County jail.
The baby's mother, 29-year-old Amber Peveler, surrendered to the Sumner County jail on Thursday.
Peveler faces aggravated child abuse and reckless endangerment charges, for attempting to purchase drugs while with her other daughter, 2-year-old Lailah Peveler.
Bond for Peveler has been set at $100,000.
No bond has been set for Beaty. If convicted of first degree murder, Beaty could face life in prison or the death penalty.
Both Peveler and Beaty are set to appear in court on Feb. 24.
