Middle school teacher's wife accused of cleaning up blood in double slaying

CEDAR HILL, Texas -- Investigators say the wife of a Dallas-area middle school science teacher has been arrested for allegedly helping her husband clean up blood in a double murder he is accused of committing after a Halloween party. 

Mansfield City Jail records show that Cary Heath’s wife, Tiffany Heath, was being held Friday on a charge of tampering with physical evidence. Her bond is set at $5,000.

Fort Worth police arrested her on Thursday in connection with last Sunday’s slayings of Daniel Derek Haros and Phillip Michael Evans, who were reportedly the couple’s neighbors.

Cary Heath, 35, was charged with capital murder of multiple persons and arrested Monday at Permenter Middle School in Cedar Hill. His bond is $1 million.

An arrest affidavit for Cary Heath obtained by CBS DFW says that a few minutes after the shooting, Heath ran into his neighbor’s home, handed his one-year-old child to the neighbor and said, “This is the last time I will see the baby. I killed two people.”

He allegedly also told his wife about the killings and told her she needed to clean blood out of their gun safe, the station reports.

The next day, he reportedly returned the school to teach class.

A student tells CBS DFW that Cary Heath seemed “completely normal,” as though it was just a regular day at school.

Heath was reportedly arrested later that day in the campus parking lot after students left.

Investigators are seeking a motive for the killings. According to the affidavit, the two victims had a short, amicable chat with Heath and his wife at a Halloween party, before Haros and Evans walked home, the station reports. Cary Heath then allegedly went to his home, and moments later neighbors heard gunshots.

The two victims were later found shot to death outside a nearby home. They also sustained blunt force trauma to the head, the station reports.

Online jail records don’t list an attorney for Tiffany Heath. She reportedly posted bond and was released from custody.

Cary Heath has reportedly been placed on administrative leave.
