A New Jersey woman was out for a jog when she was allegedly attacked and left for dead in lake, officials said.
The body of Caroline Cano was found Sunday morning in a lake in Jersey City's Lincoln Park, the Hudson County prosecutors said.
The city's medical examiner's office ruled her death a homicide, prosecutors said, though they declined to release more information on the manner of death.
Cano, 45 of Jersey City, lived a few blocks from the park, and her roommate said she went for a jog every morning before going to her job as a nanny, reported ABC New York station WABC-TV.
"They realize something was wrong when she didn't show up to the church," neighbor Frankie Ramos told WABC-TV. "She never missed a day."
No arrests have been made, prosecutors said Thursday.
Investigators are recovering as much surveillance video as possible to retrace her steps and Jersey City police officers and Hudson County Sheriff's officers have stepped up patrols in the park.
Anyone with information is asked to contact the Hudson County Prosecutor's Office at 201-915-1345.
