What to Know
Karina Vetrano's beaten body was found Aug. 2 in a marshy park in Queens.
Her family and supporters rallied on Thursday to mark six months since her death.
Police say a person is in custody, but didn't release any further details.
A man is in custody Saturday in the death of Karina Vetrano, who was killed while jogging in a park in Queens, police sources tell NBC New York.
Vetrano, a 30-year-old avid runner, had been beaten, strangled and sexually assaulted on Aug. 2 in Howard Beach.
Detectives found the man in Brooklyn with the help of forensic evidence after looking at more than 200 suspects that fit a certain profile. Police sources say the person's DNA matches the DNA profile retrieved from Vetrano.
The man was interviewed on Tuesday, and he volunteered a DNA sample and the results came back Saturday, sources say.
Police Release New Video of Karina Vetrano on Day She Went Missing
Police sources say that the person in custody has an arrest history, but nothing of a sexual nature that would have made detectives focus on him specifically.
Vetrano's father Phil usually ran with her, but stayed home with an injury the day she was killed.
A video released in September shows Vetrano jogging near her Howard Beach home the day she disappeared. Her body was later found in a marshy area just off the trail at Gateway National Recreation Area.
A GoFundMe page set up after Vetrano's death has raised nearly $290,000 toward the investigative effort.
Her family held a rally on Thursday to mark six months since her death, and asked the state for additional DNA testing that day.
Phil Vetrano didn't immediately respond to a phone message and text seeking comment Saturday night.
