Firefighters control a a fire that started in an abandoned warehouse at Jefferson Street and Dixie Highway on Thursday.

A fire at an abandoned warehouse on Dixie Highway shut down parts of the road Thursday afternoon as it threatened a nearby chlorine storage tank.

The fire at Jefferson Street and Dixie Highway was reported at 2:34 p.m., and firefighters had it under control within about half an hour, said Martin County Assistant Chief Joseph Ferrara.

Hazardous-materials crews responded as a precaution, but the chlorine tank was not affected by the fire.

Dixie Highway was closed between Jefferson Street and Hawthorne Street.

No injuries were reported. Fire investigators were at the scene, working to determine the cause.

Then Det. Carlo Sciandra found it: a handgun and three loaded magazines resting on top of the valve flap.

That’s what Sciandra explained in the report detaling Murray’s arrest on Tuesday.

The week before, deputies responded to the 3700 block of Adriatic Lane in Jensen Beach, where a man reported more than $10,000 in jewelry and a semi-automated handgun stolen from his home.

The man told deputies that Robert J. Murray Jr. was at the home before the burglary alarm went off and the items were discovered missing at about 12:30 p.m. on Dec. 18, according to a sheriff’s report.

Deputies later learned that Murray was staying at a Holiday Inn, where they headed for an interview.

During the questioning, an investigator asked to use the restroom, the report states. But when Sciandra couldn’t flush the toilet, he lifted the tank cover to see if he could fix the problem.

Then he found the stolen handgun, he said.

Murray later admitted to stealing from the Jensen Beach man, deputies said. He is being held at the Martin County jail on $25,000 bail and faces felony charges of grand theft and theft of a firearm.
