RICHMOND, Va. (WTVR) -- The mother of a Richmond toddler who died after a sexual assault spoke to CBS 6 Crime Insider Jon Burkett following her daughter's death.

Nariah Brown was 17 months old.

The toddler died Friday from injuries she suffered after a violent sexual assault at a South Richmond motel, police said. Her mom, Aija Brown, said she left her daughter in the room with a person she trusted.

Police confirmed a person of interest in the case was jailed. He was arrested by US Marshals on a probation violation, Crime Insider sources told Burkett.

Nariah born prematurely, and for three months, fought to live.

Aija Brown said she never missed a day at the hospital, and pledged to her baby girl that she would never leave her side. A promise she said she kept until the very end.

"I was giving my baby CPR in the back seat,” Brown said. "Because I thought she wasn't breathing."

While no one has been charged yet in Nariah's death, Crime Insider sources told Burkett charges will soon be announced. The cause and manner of Nariah's death has not yet been released.
