LENEXA, Kan. (AP) — A 27-year-old man charged with the shooting deaths of a man and his stepson in suburban Kansas City told police he killed them after they kidnapped him.

Alexander W. Brune of Lenexa has been charged with two counts of first-degree murder in the July 9 deaths of 47-year-old Brian Baskind and 79-year-old Clifford Preston. The men were found stabbed to death inside a Lenexa home.

Prosecutors say Brune, who’s jailed on $2 million bond, killed the men during a burglary and attempted robbery.

The Kansas City Star reports  that court documents released this week show Brune called police that night after being shot in the abdomen and told police the men kidnapped him, drove him to a house and that he stabbed both men while trying to escape.
