The person who sexually assaulted and killed a jogger in New York City this summer would likely have to answer for the many scratches sustained during the attack, police said Tuesday in releasing a profile of a suspect. Karina Vetrano's attacker left DNA on the body of the victim, who was likely trying to defend herself by scratching, Newsday reported.

The body of Vetrano, 30, was found Aug. 2 in a park and off a jogging trail in the Howard Beach neighborhood of the Queens borough of New York City. There was evidence she was sexually assaulted before being killed. Hundreds of tips have been fielded by detectives to no immediate avail.

"The person who committed the assault is likely familiar with the park for days, weeks, or months before the assault and was likely a familiar face to others who use the park on a regular basis," the police report read in part. "Following the assault on Karina, he likely stopped visiting or living in the park abruptly. He may have moved his recreational activities or residence to another area of the borough."

The report went on: "It could have appeared that he was in some type of fight or accident. He may have given any of a variety of excuses for his appearance."

Many theories surrounding Vetrano's death have emerged since her body was found. They include several offered by her father, who has said there is an unidentified female witness who was seen on a video recorded in the same park on that fateful day.

The NYPD has maintained that it is confident the killer will be apprehended and brought to justice.

Vetrano was reported missing Aug. 2 when she did not return home from her afternoon run. Her father then contacted the police, which found her body off of a local running trail in Spring Creek Park. There was evidence she was strangled, beaten and sexually assaulted.

A GoFundMe page was set up following Vetrano’s death in an effort to add to the $20,000 reward money police was offering for bringing her killer to justice. Since Aug. 9, the page has garnered nearly $289,000 in donations.
