ZIHUATANEJO, Mexico — A newspaper editor was found dead in a hotel room in this Pacific resort city, a day after running stories about organized crime and corruption in the city government.

Misael Tamayo Hernandez, editor of El Despertar de la Costa, was found early Friday nearly naked, with his hands tied behind his back, in a room at the Venus Motel, Zihuatanejo police officials said.

He was lying on a bed, covered only with a sheet, and investigators found three puncture marks on his body, one in his right hand and two others in a forearm. The cause of death was a heart attack, forensic investigators said.

Tamayo Hernandez, who was well-respected in the local journalism community, published a story on Thursday alleging that city officials gave illegal discounts on water services to individuals and businesses. The same edition also contained stories on organized crime.

Workers at the motel said they saw the editor arrive in a gray Volkswagen Jetta about 1:25 a.m. local time Friday, and that the car left at 2:30 a.m. Tamayo Hernandez's body was found at about 7:30 a.m., District Attorney Raciel Gonzalez said.

Numerous journalists have been attacked or killed in recent years in Mexico, presumably as revenge for unfavorable reports on criminals, including drug traffickers and corrupt government officials.
