A Rockville woman has been charged with murder in connection with the death of her two-month-old daughter nine months ago, police announced Thursday.

Rebecca D. Briones, 31, of the 200 block of North Adams Street, allegedly told police that she had shaken Lissana Briones and threw her on a bed before she died in February, according to a Montgomery County police press release.

Police say she also told them she previously abused her daughter in a similar manner three times before that.

Briones had called 911 at about 8 p.m. Feb. 18, saying her daughter was unresponsive. Rockville police and other rescue personnel responded and brought Lissana to a local hospital. She was later flown to Medstar Georgetown University Hospital in Washington, D.C., where she died Feb. 21.

The chief medical examiner’s office in Washington conducted an autopsy that day, but didn’t determine the manner of death until Sept. 25, ruling her death a homicide caused by multiple blunt force injuries, according to police.

Montgomery County police detectives interviewed Briones on Dec. 11, and she allegedly acknowledged the abuse, the press release said. She told police she immediately called 911 after finding Lissana unresponsive during a nap.

Police obtained a warrant on Tuesday and arrested Briones on Wednesday at the Montgomery County Public Safety Headquarters in Gaithersburg.

Briones faces charges of second-degree murder and child abuse resulting in a death, police said.
