Police believe this incident is unlikely the first time Melquisedec Chan, 52, has engaged in such acts and have urged other potential victims to come forward.
It started when the woman became sick. She told police she thought the pastor practiced medicine in Mexico, so she invited him to her Edinburg home so he could treat her illness.
She claims that’s when he injected her with an unknown substance and left her unconscious, police say.
Chan is charged with aggravated sexual assault, a first-degree felony, and practicing medicine without a license.
