The man who told prosecutors that he conspired with Jacob Heimroth in the killing of a Lansingburgh couple took the stand Thursday in Rensselaer County Court. 

Daniel Reuter took a plea deal in exchange for testimony against Heimroth, who faces life in prison for the 2014 slaying of Allen and Maria Lockrow inside their Lansingburgh home. 

Reuter testified he was "bothered" Allen Lockrow had a wife because he was dating Reuter's aunt.

Reuter says he and Heimroth drank all day and took cocaine, and planned to go "rough up" Allen on August 19, 2014. 

This is the second time Heimroth has been charged with murder in the case. His first indictment was thrown out because of a lack of evidence. He was re-arraigned when Reuter agreed to cooperate.
