An Amber Alert for San Ardo teenager Eunice Serrato remained in effect Monday as officials added a new name to their wanted list in the bizarre double murder and kidnapping.

Officials say Serrato, 16, was kidnapped by her boyfriend Juan Manuel Salazar Jr., 19, and Monterey County sheriff's detectives believe they may have headed to Mexico.

Deputies say the couple may be accompanied by a "person of interest," Rogelio Aviles, 21, described as about 5-foot-5, 150 to 170 pounds, with black hair and brown eyes. Aviles is linked to a tan 2007 Honda Civic, license number 6JUK098.

The manhunt follows the discovery of two dead men at a San Ardo home late Saturday night.

Deputies said owners Jose and Marina Serrato returned to their home at 62240 Railroad Ave. about 10 p.m. and found the bodies of Hector Reyes, 33, and Daniel Fraga, 35, in the bathroom of the house, dead of gunshot wounds. Deputies said the victims have no known relationship to the homeowners.

Their deaths are being investigated as homicides, and no motive for the killings has been offered by officials.

The Serratos' daughter Eunice was missing from the house, deputies said, and an Amber Alert was issued for her.

Serrato's boyfriend and his father, Juan Manuel Salazar, 39, both of Paso Robles, were being sought as persons of interest in the case, deputies said. The elder Salazar later turned himself to officials in King City.

Salazar Jr. is described as 5 feet, 6 inches tall, weighing 170 pounds, with blue eyes and black hair.

Serrato, deputies said, is 5 feet, 5 inches tall, weighs 130 pounds, with brown hair and brown eyes. She was last seen wearing a white and blue shirt, pink jacket and blue jeans.

Anyone with information regarding this case is asked to call Sheriff's Det. Brett Speirs at 755-3805 or the TIP line, (888) 833-4847.
