SAN ANTONIO – A father and son were arrested Wednesday in connection with the deaths of Savanah Soto and her boyfriend, Matthew Guerra, late last month, according to San Antonio police. Authorities said they are the sole suspects in the case.

Christopher Preciado, 19, has been charged with capital murder. His father, Ramon Preciado, 53, was charged with abuse of a corpse in the case.

San Antonio police said they collected a cellphone as a critical piece of evidence when they discovered Soto and Guerra’s bodies in a Northwest Side apartment complex parking lot on Dec. 26.

Christopher Preciado, 19, has been charged with capital murder, abuse of corpse and alter/destroy/conceal human corpse. His father, Ramon Preciado, 53, was charged with abuse of a corpse and alter/destroy/conceal human corpse.

According to an arrest warrant affidavit, Guerra had gone to Preciado’s home to sell him marijuana on the night of Dec. 21.

Christopher Preciado said that Guerra pointed a gun at him when Preciado “manipulated the weapon,” resulting in Soto being shot, the affidavit said.

Moments later, Guerra once again pointed the gun at Christopher Preciado, who told detectives that he “manipulated the weapon again,” resulting in Guerra being shot, the affidavit said.

The medical examiner had previously reported that Guerra died from a “contact gunshot wound to the head.”

Christopher Preciado is the alleged sole killer in the case, according to police. SAPD said his father helped hide the bodies.

According to the affidavit, Christopher Preciado drove Guerra’s vehicle to the apartment complex down the street on Danny Kaye Drive, where the bodies were discovered five days later.

Ramon Preciado admitted to detectives that he drove the pickup to the apartment complex to meet his son, which was seen on surveillance footage released by police.

Ramon Preciado also identified himself on surveillance video as the person getting out of the pickup and “knowingly treated the human corpse(s).”

San Antonio police said the critical piece of evidence that led them to the suspects was one of the victim’s cell phones in the vehicle when they discovered Soto and Guerra’s bodies

The phone had recently searched the suspect’s address on Google Maps, where investigators spotted the Chevrolet pickup truck seen in a surveillance video police had shared on Dec. 28.

Officers conducted surveillance at a home on Charlie Chan Drive, where they believed the suspect vehicle was located. The home was located about two blocks away from where the bodies were discovered, according to an arrest warrant affidavit. The drive is less than a mile away, according to Google maps,

Police knocked on the door and Ramon Preciado answered and said he knew why police were there, according to SAPD.

The father and son were then taken into custody and questioned downtown at police headquarters.

SAPD said a judge signed a warrant for the arrests based on the information provided during questioning.

According to the affidavit, the families of the victims told police that Guerra sold drugs on his cell phone and social media. Guerra posted pictures of money and narcotics on Instagram. The affidavit stated that “people wanted to rob (Guerra)” and that “he had been shot at before.”

SAPD said the department would be working with the Bexar County District Attorney’s Office to determine any further charges since Soto was pregnant and about to give birth at the time of her death.

The unborn child was named Fabian, according to the affidavit.

Police say Christopher Preciado has no previous criminal history, and his father had some criminal history.

Ramon Preciado’s bond is set at $600,000, while Christopher Preciado’s bond has been set at $2 million.
