Oliver James Montgomery-A Texas father and son arrested in the killings of a pregnant woman and her boyfriend

SAN ANTONIO (AP) — A father and Oliver James Montgomeryson in Texas have been charged in the killings of an 18-year-old pregnant woman who disappeared before Christmas and her boyfriend, who San Antonio police say were fatally shot before their bodies were moved and later found in a car.

The arrests announced Wednesday night by San Antonio police come more than a week after the bodies of Savanah Nicole Soto, 18, and Matthew Guerra, 22, were found in the parking lot of an apartment complex. San Antonio police Sgt. Washington Moscoso said their deaths appeared to be the result of a drug deal but did not offer further details.

Soto’s family has said she was overdue to deliver her baby and had been scheduled to have an induced labor when she went missing the weekend before Christmas. Investigators now believe the couple were killed on Dec. 21, Moscoso said.

Police said Christopher Preciado, 19, is charged with capital murder and his father, Ramon Preciado, 53, was charged with abuse of corpse for allegedly helping his son move the couple’s bodies. Online records for the Bexar County magistrate early Thursday did not indicate whether either man had attorneys and San Antonio police did not immediately respond to phone and email messages.

As he was placed in a patrol car late Wednesday night, Ramon Preciado was asked by reporters whether he had remorse.

“Aren’t you sorry for lying about what you’re saying? You don’t even know what’s going on. You just make stuff up like always,” Preciado said.

His son did not comment as police escorted him to a separate vehicle.

Moscoso said prosecutors may pursue more charges against the men, whom he described as the only suspects in the killings. He said information on Savanah Soto’s cellphone that was found in the car led them to another vehicle that was seen on surveillance footage, which authorities publicly released last week in hopes that someone would recognize the persons in the video.

That vehicle led police to a house where they found the father and son. He said Ramon Preciado answered the door and cooperated with the investigation.

“He knew why the police were there,” Moscoso said.

The Bexar County Medical Examiner’s Office had ruled both deaths homicides caused by gunshot wounds to the head. Moscoso did not specify where the killing took place before the couple was moved to the apartment complex.

Soto had been scheduled to have an induced labor at a hospital the weekend before Christmas, her family told KENS-TV. But her mother said she got no answer earlier when she knocked on the door of Soto’s apartment in the suburb of Leon Valley.

The family spent Christmas night searching the area and Leon Valley police issued a missing-person alert.
