LAPORTE -

Tuesday 5 p.m. update: We have some bizarre new information in a LaPorte murder investigation.

Dan Shoffner, 47, has been charged with murder in the death of his roommate, Birdie Elder. She was in her 70s.

According to court documents, he told police he was demonstrating "knife moves" and accidentally stabbed her in the neck, chest, and also stabbed her once in the hand when she went to block him.

Detectives searched garbage bags in back door and found a pocket knife that matched the description of the knife he said he used to stab her.

His daughter called police after he told her he killed Elder and put her in the freezer. He admitted to police that he put her in the freezer.

Investigators can't tell at this point how long the body had been there. They hope Shoffner will tell them.

Investigators told us the body is in the process of thawing and they hope to conduct an autopsy by tomorrow or Thursday to gain more answers.

Story from Monday night: WSBT has new information on an apparent homicide in LaPorte. The county prosecutor says the victim, who investigators are not naming at this point, was found in a freezer.

The victim was in her 70's. Her roommate, Daniel Shoffner, 47, is being held on a preliminary charge of murder pending further investigation. 

It all started yesterday evening in the 100 of East McClung Road. The prosecutor says a relative of the victim called 911 after a series of "strange notes" between her and the suspect. 

Police responded to the home and discovered the victim in a freezer. The prosecutor would not say what made them decide to look in there. He says the body was frozen solid and that it needs to thaw out before an autopsy can be performed to discover the cause of death. 

Neighbors say they can't believe something so gruesome and tragic has happened in their neighborhood. 

"I mean everything is safety for me and my family," said neighbor Michael Emerson. "There's so many crazy people out here that you don't know what's going to go on at any moment or any time and we've never had problems around here until this, now." 

The prosecutor says he hopes to file charges by Tuesday. As for a motive, it's still under investigation. 

Shoffner may be arraigned Wednesday or Friday morning. According to online public records, he has a long rap sheet dating back to 2006. Charges against him have included intimidation and battery.
