Each Of Us Just Basically Does Our Own Thing Around Here

The roommates assumed that the new girl just loved watching television:

The boyfriend had a “very possessive” streak that “stressed out” McCallum, who recently moved into the apartment after her sophomore year at Mills College in Oakland, Calif., the sources said.

She was last seen Thursday morning by four friends who had slept over in the eighth-floor apartment at 4 Washington Square Village after a party to celebrate her father’s wedding, one of the friends told The Post.

The friend said McCallum was supposed to join them at the beach Thursday, but backed out to help her father prepare for his honeymoon.

Investigators believe the unidentified boyfriend confronted her later that day about not being invited to the party.

One of the roommates saw him washing his hands in the kitchen that night, which is about the time police believed she was murdered. He then left abruptly.

The two roommates told police they hadn’t seen McCallum for days, but apparently never tried to enter her locked room, even though the TV was playing.

On Sunday, the apartment began to smell and the roommates called the super, who notified police. Cops entered from a fire escape, and found her decomposing body wrapped in a sheet on the floor between her bed and a wall. Police said there was no sign of drugs or forced entry.
