Police are searching for a suspect accused of beating an elderly man to death with a baseball bat in San Bernardino County.
The suspect was identified as Ronalee Barrett Stanberry, 37, according to the Fontana Police Department. The victim was only identified as a 79-year-old man.
On Jan. 10, police responded to an assault at Allstate Insurance on the 9700 block of Sierra Avenue in Fontana shortly before 9 a.m.
