NEWARK, N.J. (CBSNewYork/AP) — There’s still no sign of a man with outstanding arrest warrants two weeks after police say he avoided capture by slipping into a sewer system in New Jersey.

Authorities have been searching for Keith Jean, 31, of Roselle since Aug. 3 when he was a passenger in a car Harrison police pulled over.

Authorities said the man jumped into the Passaic River, climbed onto a support on the Bridge Street Bridge, jumped back into the river, and swam to a storm drain that he then walked into.

Police say Jean entered a pipe that’s connected to the Passaic Valley Sewerage Commission’s treatment plant in Newark.

Police had opened a manhole near Rt. 21 and were searching a sewer for the suspect.

A camera-equipped robot failed to find any sign of Jean in the pipe, where deadly gases gather amid chemicals, bacteria and human waste.

Cadaver dogs have found nothing, and family and friends have not asked about him.
