A New York man who confessed in a TV interview to killing his parents and burying them in their backyard eight years ago is now facing murder charges.

In footage obtained by USA TODAY, Lorenz Kraus sat down with a CBS6 reporter in Albany on Thursday, Sept. 25, one day after police found his parents' bodies.

"I buried them in their property," Kraus said of his parents after the reporter asked him what he did to them.

Kraus said he suffocated his father, after which he says his mother laid her head on his chest for a few hours and then: "I finished her."

He explained that he killed his parents out of mercy because of their failing health, and says they were both aware that he was killing them.

Now Kraus is behind bars. Here's what to know.

When was Lorenz Kraus arrested?

As Kraus left the interview at the news station, police in Albany arrested him on two counts each of second-degree murder and concealment of a corpse.

Albany police said in a Facebook post that detectives conducted a search warrant at the home of 92-year-old Franz Kraus and 83-year-old Theresia Kraus in upstate New York on Tuesday, Sept. 23, as part of a financial crime investigation.

Police said that the couple had not been seen or heard from in several years and that their son "had been collecting their social security benefits and using the funds for his own personal use."

The next day, police say they found the couple's bodies buried in the back yard. The day after that is when Lorenz Kraus reached out to CBS6 and agreed to the interview, during which he confessed to killing his parents in 2017.

Kraus' attorney pleaded not guilty on his behalf on Friday, the Washington Post reported.
