1989 – Mark J. Kilroy is murdered by a cult led by Adolfo Constanzo

Adolfo Constanzo first began gathering his cult in the 1980s. In 1986, he demanded that the Calzadas family cartel accept him and his followers into its ranks. When they rejected him, members of the family began to go missing – Constanzo and his followers were kidnapping them then killing them in gruesome magical rituals.

Constanzo enjoyed some success as a criminal, largely due to the fact that he scared the living crap out of people, but the abduction and murder of American student Mark J. Kilroy in May 1989 was the beginning of the end for his group. Diplomatic pressure from the US led to a crackdown by Mexican police, and several of Constanzo’s people were arrested. Constanzo and a few others escaped, only to be cornered by police in July. Constanzo committed suicide rather than go to prison.
