A 71-year-old Florida woman is facing an attempted murder charge after authorities say she tried to kill her husband following his receipt of a postcard from a woman he dated six decades ago.

The woman was booked into the Miami-Dade County jail on Monday on charges of second-degree attempted murder, aggravated battery and tampering with a witness in connection to the alleged weekend attack on her husband, online records show.

According to information from North Miami Beach police, the woman and her husband, who have been married for more than five decades, got into a dispute after a woman he dated 60 years ago sent him a postcard.

A probable cause affidavit was not posted online in Miami Dade County Criminal Court Tuesday, but according to WPLG-TV, officers arrested the 71-year-old woman on Sunday afternoon at the couple's apartment in a gated community in Eastern Shores in northeast Miami Dade County.

They found a head in her fridge.She blamed her husband. Now the Brooklyn woman is charged in the case.

A not-guilty plea

Court records show the woman appeared before a judge Monday for a pretrial hearing and pleaded not guilty to all three charges.

The postcard, according to a portion of the report read aloud in open court by Judge Mindy Glazer during the hearing, upset the suspect so she allegedly tried to smother her husband with a pillow.

During the hearing, recorded by NBC, a prosecutor said the woman also admitted to police she urinated on her husband.

Detectives also wrote in the report the victim was "extremely fragile" after the attack and had “several serious bruises and open lacerations" and "open bite marks that were bleeding," the judge said.

The 71-year-old woman was charged with tampering with a witness because she allegedly took his cell phone from him around the time of the attack, the judge said.
