UTICA — Authorities continue to probe a Monday fatal shooting on Lincoln Avenue that so far has been deemed 'justifiable.'

"We still have a lot of work to do" in terms of investigating the incident, Oneida County District Attorney Scott McNamara said Tuesday.

Around 5 a.m. Monday, Utica police responded to 1303 Lincoln Ave., where they found Shatelle Hooks, 35, of Syracuse, suffering from multiple gunshot wounds.

Hooks later died at an area hospital.

Later in the day, officials announced that off-duty Albany police officer Christofer Kitto had shot Hooks, but wouldn't face any charges other than a misdemeanor count of patronizing a prostitute.

Witnesses told police Kitto was at the residence when an altercation with Hooks began. It was during the altercation when Hooks allegedly displayed a knife and attempted to rob Kitto.

Police said Kitto was in possession of more than more than $3,000 in cash at the time.

It was then that the shooting happened.

Hooks has been determined to be the boyfriend of a woman at the residence and "complicit in her prostitution activities," McNamara said.

"We had to make a decision based on evidence we had ... that he was justified in his actions," McNamara said of the Monday decision. "In this case, a knife was located at the scene. ... (Kitto) could not have retreated."

McNamara said Kitto had been in the area visiting Turning Stone Resort Casino.

"At some point in time he went onto a website that advertised prostitution," McNamara said. "That's where he found her."

But, on Monday, based on the evidence at hand, the district attorney said Kitto's actions and use of force was justified.

"The next step for this case, when we receive all the evidence, we will have to sit down and make a decision whether we believe based on the totality of evidence that he was justified in shooting Hooks," McNamara said.

According to an Albany police spokesperson, Kitto is on administrative leave while Utica police conduct their investigation. He has been on the police force for five years.

The woman who lives at the residence has not been charged with anything.
