A tip, a welfare check and an arrest

Police have not yet said how long they believe the body had been in the fridge.

Officers initially responded to a tip from someone who said they saw what appeared to be a human head in a black bag in the refrigerator of Stines' home, according to court records and information obtained by the New York Times and the Associated Press.

USA TODAY has requested the police report from the Kings County Criminal Court clerk's office, where online records show it was filed.

When officers visited Stines' home, the Associated Press reported, they found multiple black bags in the refrigerator and freezer full of body parts.

"The refrigerator was taped shut at the time," Joseph E. Kenny, NYPD chief of detectives, said after the find the Times reported and − according to the police report, Stines pleaded with the officers not to open it."

According to police, Stines told detectives the body had been in the fridge "for several months" and belonged to a man who her husband had an argument with over drugs in September, the Times reported. The woman allegedly told investigators her husband killed the man and put his body in their refrigerator.

Two days after the body was found, on Jan. 24, police said they arrested Wells in connection to the finding.

After her arrest, Stine was taken for a psychiatric evaluation at a local hospital then was later booked into jail.

So far no other arrests made in case

As of Monday, police told USA TODAY no other arrests had been made in the case.

The suspect's 79-year-old aunt, Aime Stines, told the Times her niece moved to New York City around eight years ago after her father died and had "a history of drug use but never appeared to be violent."

“There is no way − I couldn’t believe it,” Stines told the Times she recalled after her niece’s arrest. “Heather was always smiling and talking. She has this voice where she talks so fast that I can hardly understand her. She always seemed happy.”

A $50,000 bond and a not guilty plea

Court records show Stines pleaded not guilty to the charge in Brooklyn Criminal Court on Jan. 25 and was set to reappear in court Monday in connection to the case.

Records also show Stines remained in custody on $50,000 bond on Monday.
