Police early Thursday found the body of a 4-year-old girl who had been shot twice in the chest - the fifth child killed in drug-related violence in this Mexican resort city in less than a week.
The child was in a car next to a woman who had been shot three times in the back, Guerrero state police said in a statement. Police did not release the identities of the victims or discuss a possible motive for their slayings.
At least five young people have died in drug violence in Acapulco since Sunday, including a 2-year-old boy and a 6-year-old boy killed with an elderly woman who tried to shield them when gunmen opened fire at their home.
Police found more than 200 shell casings at the scene in a poor neighborhood in Acapulco, which has been the scene of bloody drug cartel turf battles. Witnesses told police a man being chased ran inside the house minutes before gunmen started shooting. It was not clear what happened to the man.
That same day two 15-year-olds were killed in separate attacks.
Children and youths have increasingly been targeted in killings or died as bystanders caught up in Mexico's drug war.
