Moore told her friend that she and Knapp got into an argument and she was waiting outside his home for a ride.

She was never seen alive again.

Knapp told police that about an hour after Moore left, he went to Harold Seltzer's Steakhouse, where he works as a kitchen manager, to complete inventory.

Police said they later discovered that Knapp took clothes to work with him and tossed them in a dumpster, which was taken to a landfill. After searching a landfill, police found the clothes, stained with Moore's blood.

Police executed a search warrant at Knapp's residence and recovered more evidence that led them to believe she was dead.

"Yes, there was blood that was identified as hers on our suspect's pants, however there is lots of blood that was located during this investigation," authorities said.

Friends say Moore and Knapp had a "turbulent" relationship and got "into fights quite often."
