Women traveled to area of suspect’s home, police say

Barthelemy’s phone communicated with a burner cellphone several times before July 10, 2009, which was the last day she was seen alive, authorities said in Heuermann’s bail application.

On that day, cell tower records show the burner phone traveled from Massapequa Park to Midtown Manhattan and later that day, Barthelemy’s phone traveled from Midtown Manhattan to Massapequa, the application says.

Barthelemy’s last phone location was recorded in Massapequa on July 11, 2009, at roughly 1:43 a.m., the court document says.

Less than a year later, on June 6, 2010, Waterman was seen on surveillance footage leaving a hotel in the area of Hauppauge around 1:31 a.m., according to the bail application. It was the last time she was seen alive.

Waterman’s phone also communicated with a burner cell phone at around the same time she left her hotel, according to the bail application.

Cell tower records show her phone traveled to Massapequa Park, with its last location recorded in that area at around 3:11 a.m. “in the vicinity of the residence of” Heuermann, the bail application says. She was never seen alive again.

In the case of Costello’s killing, police say a burner phone contacted her the day before she vanished. In those communications, the burner phone connected to cell towers in West Amityville and Massapequa Park, the bail application says.

Around the time of the communications, witnesses said “a prostitution client” went to Costello’s residence, where a person pretended to be her “outraged boyfriend” as part of a ruse and got the client to leave, the application says.

The burner phone, which was located in Massapequa Park, messaged Costello’s phone early the next day, on September 2, 2010, saying, “That was not nice,” according to the document.

Later that day, Costello was again contacted by the burner phone, which was at Massapequa Park, the bail application says. That night, the burner phone traveled to the area of the woman’s house, according to the document.

On the night of September 2, Costello walked outside her home, leaving her phone behind, and was never seen alive again.
