Investigators at the New Jersey shore on Saturday will ramp up their investigation of a motel fire that killed four people.

Arson investigators from numerous agencies are trying to determine what caused Friday’s early morning blaze at the Mariner’s Cove Motor Inn in Point Pleasant Beach. Some of the investigators also probed the cause of a massive boardwalk fire about 10 miles to the south last September.

About 40 people were staying at the motel when the Friday fire started. Some had lost their homes in Superstorm Sandy.

The identities of the people killed could be released Saturday after they are officially identified and their relatives notified.

Eight others were injured, three critically. They include a woman who sought refuge in a running shower as she waited to be rescued.
