A Texas father and son arrested in the killings of an 18-year-old pregnant woman and her boyfriend are facing new evidence tampering charges, authorities said Friday as they announced that investigators have recovered the gun used to shoot the couple who disappeared before Christmas.
The new charges in the killings of Savanah Nicole Soto, 18, and Matthew Guerra, 22, were announced two days after the father and son were interviewed by detectives and “made enough statements to implicate them in the murder,” San Antonio Police Chief William McManus said at a news conference. He'd earlier described the scene where the couple were found dead in a car as “very, very perplexing.”
