A South Jersey jury convicted a 29-year-old Cinnaminson man on all charges stemming from the grisly murder of his girlfriend and her father last year.
The Burlington County Times reports Dennis Pozniak was found guilty of two counts of first-degree murder and several weapons offenses tied to the deaths of 24-year-old Nicole Wilson and 52-year-old Bryan Wilson.
Prosecutors say Pozniak used a pipe wrench to beat both of his victims to death on Jan. 30 as they slept inside the Mount Holly home that the couple shared.
Defense attorneys argued that Pozniak didn't deliberately intend to kill the Wilsons, but years of mental illness and drug use led to his diminished capacity and inability to form intent.
