"During the assault, the suspect stole her purse, (and) left her with life-threatening injuries and unconscious," a police statement said.
Roberts died six days later from head injuries she suffered in the crime.
Earlier this month, detectives from the LAPD's Scientific Investigation Division analyzed fingerprints from some of the victim's stolen property, which was recovered a few days after the crime, police said.
"Through the fingerprint lifts, the suspect in this case was identified as Albert McKee," the statement said.
LAPD detectives went to Rochester, and they and Rochester police officers arrested McKee.
Anyone knowing more about the case was urged to call LAPD detectives Tennell or Romero at: (213) 486-6890; or (877) LAPD-24-7 |
