Suffolk County prosecutors handed over a trove of discovery material including crime scene photographs, autopsy photos and DNA evidence to the defense team representing accused Gilgo Beach serial killer Rex A. Heuermann as he appeared in a Riverhead court on murder charges yesterday.

More than 2,500 documents were provided to the defense, which includes anthropological and DNA evidence, notes from the offices of the medical examiners in New York City and Suffolk County and photographs from the crime scenes where the remains of the three women Heuermann is accused of killing were found off Ocean Parkway near Gilgo Beach in 2010, Assistant District Attorney Nicholas Santomartino said in Suffolk County Court.

The discovery material also includes hundreds of hours of surveillance footage from around Heuermann’s Massapequa Park home, a storage facility where he kept belongings, outside Heuermann’s Manhattan office and video connected to victim Megan Waterman, said Santomartino, who was joined at the prosecution's table by Suffolk County District Attorney Ray Tierney.

“It’s quite voluminous,” Santomartino said of the list of evidence provided in the form of a 2-terabyte hard drive and six disks to Heuermann's lead defense attorney Michael J. Brown. The 6’ 4”, 59 year old Heumermann, dressed in a dark blue blazer over a light blue shirt and tan pants, did not speak during his brief Tuesday afternoon courtroom appearance in Riverhead. Before the public proceeding began, the lawyers met for 32 minutes in the chambers of State Supreme Court Justice Timothy Mazzei, the judge presiding over Heuermann's prosecution.

Heumermann has pleaded not guilty to first- and second-degree murder charges in the killings of three women.

A 14-month-old girl has died on Long Island after police said her grandmother had forgotten to drop her off at a daycare center — and instead left her alone inside her sweltering hot SUV for eight hours. Suffolk County police officers were called to Redwood Lane near the Long Island Rail Road station in Smithtown around 4:20 p.m. Monday for a report of an unresponsive child. The toddler was rushed to Saint Catherine of Siena Medical Center, where she died. Snejana Farberov reports in THE NY POST that an investigation has determined that the baby’s grandmother, a 54-year-old woman from Greenlawn, was supposed to take her granddaughter to a daycare Monday morning.

Instead, the woman headed straight to work, “leaving the child in a car seat in a back seat,” the Suffolk County Police Department said in a press release. About 8 hours later, the grandmother went to pick up the tot at the daycare on Redwood Lane, only to realize that she had left her grandchild inside her maroon 2018 Jeep Cherokee.

The grandmother, who has not been named, was not charged in the girl’s death as of yesterday. But police told The Post the investigation is ongoing.

Temperatures in Smithtown reached 83 degrees during the day Monday, according to AccuWeather.com.

When the outside temperature is around 80 degrees, the in-car temperature could reach a scorching 123 degrees after just one hour.
