Two San Antonio teenagers have been arrested and charged with capital murder in connection with one of their own mother’s killing, after the woman was found slain on Tuesday in what was at first thought to be a robbery gone bad.

Matthew Dempsey and Daniel Saucedo, both 18, are accused of murdering Mary Dempsey, 53, according to the San Antonio Police Department. Dempsey was arrested on Tuesday, while Saucedo was picked up on Wednesday.

Police said Mary Dempsey, who lived on the 7500 block of Stagecoach, didn’t go to work on Tuesday, and so her employer phoned one of her relatives to go and check on her, local ABC affiliate KSAT reports. The relative then found her corpse in her living room. Dempsey’s vehicle was also missing from her home.

Deputies originally responded to the scene thinking it was a botched robbery, the San Antonio Express-News reports.

"We can't confirm that she died by gunshot or cutting, but what we can tell right now is there's obvious trauma to the body," San Antonio Police spokesman Doug Greene said Tuesday, according to the paper.

Eventually, police reported that they located the victim’s car, and Matthew Dempsey was brought in for questioning after detectives started looking into him as a potential suspect, according to the Express-News. The interview was allegedly enough to bring charges against him.

On Wednesday, police announced that they had arrested Saucedo in connection with the murder, as well.

"It's a heartbreaking story," Greene told the Express-News. "To find out that it was the son of the victim involved in this, it's just kind of hard to process but the evidence shows otherwise and we have to go by the evidence."

The San Antonio Police Department would not comment on how Saucedo was arrested in connection to the crime, however.

Neighbors told the Express-News that robberies have been common in their area for years.

"If we don't hear [police] helicopters at night, it's unusual," neighbor Johnny Arredondo said.
