The reward for information leading to an arrest in connection with the death of a Queens jogger has doubled to $20,000.
30-year-old Karina Vetrano disappeared last Tuesday after going out for a run in Spring Creek Park near the Belt Parkway.
Authorities say her father later discovered her body in a marshy area in Howard Beach.
The NYPD says it has created a special task force to investigate leads and is reviewing surveillance video from businesses in the area.
Forensic evidence from the crime scene is also being analyzed.
Investigators say Vetrano was sexually assaulted, beaten and strangled.
