TROY (AP) - Two men were arrested Saturday on murder charges in the deaths of two women and two children who were found dead in their upstate New York apartment.

Justin Mann and James White were arrested in their hometown, Schenectady, and pleaded not guilty in Troy City Court.

According to the Times Union, Troy Police Chief John Tedesco said one of the defendants knew one of the victims. He declined to elaborate.

Information given in court said the killings took place at about 9 p.m., Dec. 21. It wasn't until Tuesday, five days later, that a property manager found 36-year-old Shanta Myers; her children, 11-year-old Jeremiah Myers and 5-year-old Shanise Myers; and 22-year-old Brandi Mells in a basement apartment along the Hudson River, just north of Albany. Police say Myers and Mells were in a relationship.

Tedesco and District Attorney Joel Abelove, who appeared at a press conference, declined to answer questions about a possible motive and the method of the killings.

They also would not say how the defendants know each other, but said that both have records and Mann is on parole.

More than two dozen people were in court Saturday, some wearing Troy Boys & Girls club sweatshirts.

Mann appeared to break down as he was led out of court. A man and a woman in the courtroom became visibly distraught.

The suspects were sent to the Rensselaer County Jail to await their next court appearance, on Thursday. Neither man said anything as the charges were read.

Tedesco said no more arrests are expected.

"I don't have to tell you what a good feeling it is to have these two in custody," he said. "It's a great relief."
