Suspected Gilgo Beach killer Rex Heuermann was back in front of a judge Tuesday for the first time since being charged in a fourth murder.

Heuermann’s attorney Michael Brown says his client is feeling lonely and depressed after being in isolation at the Riverhead jail since his July arrest.

Heuermann’s estranged wife and daughter have come to court in the past but were not present at today’s appearance.

In court, the prosecution handed over three terabytes of data on this case to the defense. It included a total of 2,500 pages of reports and nearly 3,000 of the tips from the Suffolk County police departments logs.

Brown says the tips are important because they were informed that there may be another person that the prior district attorney was prepared to charge with the crimes, so they want to see the leads for their defense of this case.

Heuermann is due back in court on April 17.
