For eight minutes, Lorenz Kraus sat in a tan armchair inside an Albany television station’s news studio, parrying questions about the fate of his parents after the police had found two bodies buried in their backyard the day before.

He sat awkwardly, clad in shorts and sneakers but no visible socks, as the reporter pressed him. Then, the words tumbled from his mouth.

“When your parents died, did they know what was happening to them?” asked the interviewer, Greg Floyd of WRGB, a CBS affiliate.

“Oh yeah.”

“And they knew it was at your hand?”

“Well, yes, no one else’s.”

Mr. Kraus had come to the station Thursday evening to tell his version of events, days after officers, who had been investigating Social Security fraud, discovered the bodies and took him in for questioning, the outlet said. By the time the taped interview ended roughly 20 minutes later, police officers were waiting in the parking lot and arrested Mr. Kraus when he emerged, the authorities said. The station aired the interview during its 6 p.m. broadcast that evening, the station said.

Mr. Kraus has been charged with two counts of second-degree murder and two counts of concealment of a human corpse in connection with the killings of his parents, Franz and Theresia Kraus, eight years ago.

Prosecutors say that sometime between July and September 2017, Mr. Kraus strangled his parents and then buried them in the backyard of their home on Crestwood Court in the Whitehall section of Albany.
