The mother of a woman allegedly killed by a serial killer in Long Island appeared on "Good Morning America" to talk about her daughter's death.

Melissa Barthelemy, 24, of Buffalo is just one of eight bodies found by Suffolk County Police. Authorities said all of these women were victims of who they are calling the "Craigslist Killer". The women were linked to prostitution and selling those services on the popular website.

Police also said that the killer may be linked to law enforcement because of the techniques the suspect used and because of the remote location where the bodies were found. They say the person knows the area.

Authorities describe the killer as organized with above average intelligence. He lures the women, kills them and dumps their bodies in a different location. They said one unique characteristic of this killer is that he is a social person surrounded by family and friends. They also believe he appears to be "normal" to others. Usually, serial killers are characterized as loners.

"Could be law enforcement, it could be someone that works... a civil servant. It could be a code enforcement person. Could be a building inspector. Could be a post man or it could be anyone who knows the area quite well," former New York City Police Detective Wally Zeins said.

After her death, police said the killer made calls to Barthelemy's family using her own cell phone. The calls were traced back to crowded places in New York City. Police said even if the killer was caught on surveillance camera, it would be hard to pick him out of a crowd of hundreds of people also on their phones.

Police have search an eight mile stretch along the Suffolk County shoreline. Now, they are expanding that search hoping to find more clues that may lead to the killer.
