A Mexican law enforcement official says the prime suspect in the killings of 11 family members is a man who apparently sought revenge after one of the victims reported that he raped her and he was jailed.

The official tells The Associated Press that authorities believe multiple attackers shot the woman and her family, including two girls. The killers also brutally slashed a male victim believed to be the woman's partner, and may have tried to decapitate him.

The official was not authorized to be quoted by name and spoke on condition of anonymity.

Prosecutors said late Friday that two suspects are being sought in the Thursday night murders in the remote hamlet of San Jose el Mirador, in Puebla state.

Authorities have not identified the victims or the suspects.
