A Long Island mother of four who vanished more than two weeks ago was found dead in a state park Thursday – and her husband has been arrested for her murder.

Melissa Molinari, 38, was last seen at her home in Centereach, New York, on Nov. 21, according to the Suffolk County Police Department. Her vehicle was parked outside the family's residence at 45 Lolly Lane. She was reported missing on Dec. 2 by a friend, police said.

His daughter Gabby Petito's disappearance dominated national headlines for weeks before she was found slain in Grand Teton National Park in Wyoming.

Joseph Petito tweeted out a plea to the public to help find Melissa Molinari.

Petito’s family converted their original #findgabby page on Facebook into a missing persons page.

They also launched the Gabby Petito Foundation to provide resources to other families trying to locate missing loved ones.

The 22-year-old's disappearance kicked off a nationwide manhunt before her remains were found Sept. 19. A coroner later determined that she had died from strangulation. 

Her fiancé, Brian Laundrie, was later found in a Florida swamp with a self-inflicted gunshot wound to the head.
