A suspect wanted for questioning 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 taken into custody by federal authorities in Tennessee, officials said.

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.

Two guns were confiscated from the house where Knight was found in Tennessee.

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.

"It's clear that person was firing at them and was capable of seeing them from the position that they took in the yard," Detective Lt. Jack Fitzpatrick said after the shooting.

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