LOUISVILLE, Ky (WDRB) -- A tourist in town for the Kentucky Derby was shot and killed near his hotel on Phillips Lane Saturday night. Police have charged three people in connection to 49-year-old Toronto resident Scott Hunter's murder.

Friends of Scott Hunter describe him as a great guy and a lively character. He was a bartender in downtown Toronto for nine years.

"We're trying to get our heads around it and trying to comprehend how something like this could happen," said Beau Opperman, Hunter's boss at House on Parliament.

Opperman says Hunter was in Louisville with a friend for the Derby.

"He was down there to watch the race and was having a good time," he told WDRB by phone Monday. "And last we heard, he had texted or called his girlfriend and was having a great time, and then his family contacted me Sunday morning, and I can only imagine what they're going through.” 

Police say Hunter was killed as he and his friend were headed back to their hotel after the Kentucky Derby.

"It's extremely unfortunate and tragic,” said Lt. Todd Kessinger with the LMPD Homicide Unit.

Police worked on the case all weekend and arrested Fahed Abu-Diab, Fatima Abu-Diab and Tyrone Thomas Jr.

"Two are brother and sister and the third is the boyfriend of the sister,” Kessinger said.

Police say they had been committing robberies all weekend.

"They were driving down Phillips Lane and saw the two victims walking on the side of the road, and that's when they got out of the vehicle and approached them," Kessinger said. "They went to rob both victims and, during the robbery, there was a struggle, at which time they fired a shot and killed the victim."

All suspects were interviewed by police and gave statements indicating their involvement in the robberies and Hunter's murder.

Fahed and Fatima Abu-Diab are charged with murder.

Thomas is charged with complicity to murder.

All three are facing nearly a dozen robbery charges and Fatima Abu-Diab is also facing a possession of a controlled substance charge.

Lt. Kessinger says Hunter and his friend may have tried to fight off the suspected robbers before Hunter was killed.

"I absolutely think the gun was intentionally fired but I can't really get into the details of the actual struggle," Kessinger said.

One of the suspects, Fahed Abu-Diab, has a history of violence.

Police tell WDRB he was involved in the

That case was ruled a "justifiable homicide" and Abu-Diab wasn't charged.

Police say over the weekend, a detailed anonymous tip came in about Hunter's murder.

They're asking for that person to come forward so they can speak with them.

No other arrests are expected in this case.

Tyrone Thomas and Fatima Abu-Diab were in court Tuesday. Thomas pleaded not guilty to complicity to murder and Abu-Diab pleaded not guilty to murder. Their bonds were set at $500,000 cash.

Fatima's brother, Fahed Abu-Diab, was expected in court tomorrow.
