Police released a profile on Wednesday of the man they believe killed a Queens woman this summer.
Karina Vetrano was found dead in a marshy area in Howard Beach back in August, after she left her house to go for a run.
Investigators say she was sexually assaulted and strangled.
Police previously released this sketch of the man they're looking for.
They say the killer was likely familiar with the park and may have been living there prior to the assault.
Police say he was probably disheveled and possibly had cuts or scratches on his body signaling a fight shortly after the attack.
He may have also taken steps to keep a lower profile, including changing his appearance.
Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-TIPS, or text CRIMES and then enter TIP577, or visit www.nypdcrimestoppers.com.
