The suspect in the death of a 50-year-old Long Island man who was shot in the chest through the window of his Long Island home late last month was ordered held without bail Friday after he pleaded not guilty to murder.

Brett Knight, 45, was apprehended Wednesday morning by U.S. Marshals, Suffolk County homicide detectives and authorities from Tennessee's Sevier County sheriff's office. Police had been looking for Knight since the Sept. 24 shooting of Ross Reisner in Reisner's East Setauket home.

Prosecutors say Knight allegedly fired 11 shots through the window of Reisner's home.

Reisner died from the gunshot wound, while another person in the home at the time was grazed in the arm, according to the Suffolk County Police Department. Police had said the attack was targeted, and that the shooter went into the backyard and fired through the window.

Prosecutors say Knight has made "oral admissions" about his alleged involvement in the murder.

Knight's lawyer, Michael Brown, said Knight lived in the home for about seven months and had been good friends with the victims for years. He said his client was "distraught" about the death of his friend and his arrest in the case, and said Knight looks forward to fighting the charges.

Police declined to speculate on the motive. Authorities said Reisner worked as a horse trainer and may have also been involved in a construction business.
