Brett Knight Pleads Guilty to Murder for Shooting Death of Ross Reisner

Brett Knight, a 46-year-old Utah man, pleaded guilty Wednesday to murder for shooting East End equestrian Ross Reisner to death on September 24, 2013.

According to police, Reisner was home on Upper Sheep Pasture Road in East Setauket with his partner of 25 years, Kevin Murray, when shots were fired through a window into the house. Officers arrived to find Reisner, 50, with a gunshot wound to the chest and he was later pronounced dead at Stony Brook University Hospital, police said. Murray was injured in the shooting.

Just a few months prior, Reisner and Bobby Ginsberg, of Southampton Riding Club, opened Maple Tree Farm, a show barn in Mattituck.

Knight, a former tenant at the  East Setauket home, was arrested October 13, 2013, and indicted by a grand jury three days later.

In addition to first-degree murder, Knight pleaded guilty to attempted first-degree murder and second-degree criminal possession of a weapon, both felonies, as well as three counts of second-degree aggravated harassment, a misdemeanor.

Knight is scheduled to be sentenced February 4, 2015.
