How an NYPD Lieutenant's Intuition Helped Catch the Queens Jogger Murder Suspect

karinavetrano/Instagram(NEW YORK) — The arrest this weekend of 20-year-old Chanel Lewis, who is accused of murdering Queens jogger Karina Vetrano six months ago, can be chalked up, in large part, to one lieutenant’s intuition, according to police sources.

Lewis was arrested this weekend just days after the six-month anniversary of 30-year-old Vetrano’s death. Vetrano was fatally strangled on Aug. 2, 2016, while jogging alone in Howard Beach in Queens, on a path where she and her father often ran together.

According to police sources, NYPD Lt. John Russo first saw Lewis on the Brooklyn/Queens border in May, three months before Vetrano’s murder. Russo thought he seemed suspicious and called it in, but Lewis left before the patrol could respond, police sources said. The next day, a 911 caller mentioned Lewis by name and said he looked like he was breaking into a Howard Beach property with a crowbar, police sources said.

After Vetrano’s death in August, police combed through leads, but no one was arrested. As the summer ended, Vetrano’s devastated mother told ABC News she was “broken” but said she was confident her daughter’s killer would be caught eventually.

The case went cold until last week when, on a lark, Russo decided that police should consider Lewis for the murder, according to police sources.

Lewis was tracked through the 911 call that mentioned him by name as well as through three prior summonses dating back to 2013; one was for urinating in public and two others involved breaking the rules in the park where Vetrano’s body was found.

“Once we saw that he was in and around the Gateway Park area that’s when we went to speak to him,” NYPD Chief of Detectives Robert Boyce said at a news conference Monday.

Police first spoke to Lewis on Feb. 2 and Lewis voluntarily gave a DNA sample — one of 600 samples taken in the case, police said.

“We brought that immediately to the office of the chief medical examiner, where within two days we had a hit of the DNA we recovered from the crime scene,” Boyce told reporters Sunday.

Lewis was taken into custody Saturday evening, and Boyce said Monday that Lewis gave “detailed, incriminating statements” to arresting officers though he declined to elaborate.

Police sources said that Lewis confessed to the crime and that there was no motive other than Lewis was “unhinged” and apparently upset there were so many people in the apartment where he lived with his parents.

Lewis, of Brooklyn, has no criminal history and does not work, Boyce said.

Boyce said police do not believe Lewis knew Vetrano “at all.”

“From what his statements were, it was a chance encounter,” Boyce said Sunday.

Boyce said that Vetrano herself helped police identify the suspect.

“She had the DNA under her nails. She had touch DNA on her back and there was more DNA on the cell phone. So three incidences that we were able to bring this profile up and that’s how we were able to link it,” Boyce said.

After police received over 250 leads from the public regarding Vetrano’s murder, Lewis was charged this weekend with second-degree murder, police said. He made his first appearance in court Sunday and did not enter a plea. The case is being presented to a grand jury to consider sexual assault charges. His attorneys declined to comment to ABC News Monday.

Lt. Russo said Monday that it was “good old-fashioned police work” that led to the suspect.

Vetrano’s father, Phil Vetrano, told ABC station WABC-TV in New York on Sunday that “the police did an excellent job.”

Karina Vetrano’s mother, Cathy Vetrano, added, “They worked endlessly and tirelessly, and that was because of their passion, combined with our passion for our daughter.”

“We would never tire, we would never stop,” Phil Vetrano told WABC-TV.

Phil Vetrano told WABC-TV he will “absolutely” be at Lewis’ trial. “Every minute of the day,” he said.
