MEXICO CITY (AP) _ A lawyer who represented the late drug lord Amado Carrillo Fuentes is missing, news reports say.

The disappearance of Sergio Aguilar comes just three weeks after the bodies of three of Carrillo Fuentes' doctors turned up tortured, strangled, burned and stuffed in oil drums. The three had participated in the July 4 plastic surgery operation that ended up costing Carrillo Fuentes his life.

Aguilar missed a court date Tuesday in Mexico City and relatives have not heard from him, Television Azteca reported Tuesday.

A local prosecutor has opened a missing-person investigation, according to that report.

Police are still investigating the killings of the three doctors, who prosecutors say killed Carrillo Fuentes with a powerful analgesic after the drug lord underwent plastic surgery in a bid to elude police. Their bodies were found Nov. 2 on a rural highway outside Mexico City.
