A New Jersey man is in critical condition Tuesday, days after nearly drowning following a suspected electric shock in a south Jersey shore motel pool over the holiday weekend.

Witnesses say 34-year-old Greg Subiszak was spotted face down in the Aztec Motel pool Saturday night in the town of Wildwood Crest.

A teenager who tried to save Subiszak, of Fair Lawn, New Jersey, tells WPVI-TV that his body tensed up and began shaking after jumping in. A maintenance worker shut off the electricity and pulled Subiszak out. The worker and a guest performed CPR. Subiszak is hospitalized in Philadelphia.

Motel owner Adamo Pipitone says the pool will stay closed until it's cleared to reopen by county health officials. He speculates a short in a lamp post is to blame.

Police are investigating.
