The women, all in their 20s, are at the heart of the Long Island serial murder case that has captured national and global attention following the arrest of suspect Rex Heuermann just over a week ago.

The 59-year-old married father of two, an architect who worked on Fifth Avenue in Manhattan and resided in Nassau County in the village of Massapequa Park just miles north of the site where their bodies were found -- in a grassy area of Gilgo Beach, a barrier island off Long Island's south shore in the Suffolk County town of Babylon.

Heuermann was arraigned on murder charges in Suffolk County Court on Friday, July 14, for the killings of Melissa Barthelemy, Megan Waterman, and Amber Lynn Costello. He's also the prime suspect in the disappearance and murder of Maureen Brainard-Barnes.

Investigators have found 11 bodies on Gilgo Beach and identified five of them.

The time frame for the murders is from April 20, 1996 to Dec. 13, 2011.

Here's a look at the four women at the heart of the case, with information from Suffolk County Police:

Melissa Barthelemy

Last seen: At her residence, a basement apartment in the Unionport section of the Bronx on July 12, 2009. She told a friend she was going to see a man and would be back in the morning. This friend was aware she was a sex worker, but Barthelemy offered no other details. Her cellphone records show she traveled from the Bronx to Manhattan, most likely via taxi.
