Cops Arrest Alleged Killer Whose Texts Tortured Victim's Family

Police arrested the alleged killer who sent tortuous messages to a murder victim's family, giving them false hope she was alive and framing the girl's boyfriend for the crime.

Evans Ganthier, 30, was charged Monday with the brutal murder of Rebecca Koster, a 24-year-old beauty from Medford, Conn., whose mutilated body was found in a Connecticut field on Dec. 4. The Central Islip man will be arraigned today.

Ganthier allegedly sent Koster's family tormenting messages after her body was found, portraying the victim as a woman still alive crying for help. He sent a text two days after Koster's body, brutally slain and then set on fire, was discovered in the field. 

The text sent at 11:40 p.m. said: "Dan has me tied up in a basement somewhere in Commack," and police responded to the home of Koster’s boyfriend, Dan Mayor, 28.

He was the last person to see Koster before she disappeared, but Mayor was never named a suspect and never charged in connection with the crime.

The family of the dead girl received multiple texts implicating Dan. Koster's mother got a message from her daughter's number that said, "Don't tell Dan or he'll kill me."

Eventually, authorities identified the body in the field as Rebecca Koster and the girl's parents, broken and shocked in their grief, found their pain exacerbated by the tormenting texts of hope they received from their daughter's killer.

"It was torture," the girl's mother said at the time.
