Police Release Sketch in Case of Slain Jogger: 'We Feel He Was There'

NYPD officials have released a sketch of a man they believe was in the vicinity at the time of Karina Vetrano's murder.

The NYPD has released a sketch of a man they believe was in the vicinity when Queens jogger Karina Vetrano was sexually assaulted and killed August 2.

NYPD Chief of Detectives Robert Boyce said the sketch was made with the help of a utility worker who recalled seeing the person of interest on the day the 30-year-old beauty was brutally murdered.

The worker remembered the man wore a dark wool hat despite the heat of the summer day. The sight of the guy in the area took the worker by surprise, Boyce said, and he even thought for a moment that he'd been mugged.

"We want to speak to this person because we feel he was there," Boyce said of the man in the sketch.

The man is described as a black male between 35 and 45 years old, about five feet, ten inches tall with a medium build.

Boyce also announced Tuesday that police have a DNA profile of the killer, but so far, they have no matches in the national database.

Vetrano was murdered as she jogged through a marshy area near her home in Queens.

"This woman put up a ferocious fight, right to the end. She was beaten quite severely, which would suggest she put up a big fight,” Boyce said shortly after the investigation began.

News of her death, along with her many photos on social media and another eerily similar crime in Massachusetts days later, made national headlines.

Her father, Phil, a retired firefighter, had allegedly warned her not to go running in that area without him. After his daughter failed to come home, he called police and eventually discovered her body in the marsh.

"The father then went into the woods and then found the body with our detectives right after him," Boyce said. "We found her face down in the ground."

A GoFundMe campaign that was started to reward a tipster who helps lead police to the arrest of Vetrano's killer has raised more than $265,000 as of August 31.
