Syracuse (WSYR-TV) - Detectives in Cayuga County were interviewing witnesses and tracking new leads late Monday in the poisoning death of a Weedsport man seven years ago.
A new autopsy shows Michael Wallace was murdered by an overdose of ethylene glycol, a key ingredient in anti-freeze. Investigators are trying to link his wife to the crime after she was charged late last Friday with killing her second husband in exactly the same way.
Stacey Castor was arrested last Friday, after she called 911 to say her daughter had attempted suicide at the family home on Wetzel Road in Clay. The 20-year-old daughter, Ashley Wallace, was released from the hospital Monday afternoon, after being treated for an undisclosed illness.
She has now told investigators what they had already suspected, that she did not try to take her own life.
“Information that definitely establishes the fact that she did not attempt to kill herself. That there was no attempted suicide,” Onondaga County Sheriff Kevin Walsh says.
Instead, Walsh says, Stacey Castor may face additional charges in the illness of her daughter.
“I think the circumstances that led to her arrest on Friday will strengthen the overall case we have against this woman.”
The case against Castor goes back to August 2005, when her second husband, David Castor, Sr., died in the Wetzel Road home from ethylene glycol poisoning. The toxic liquid was in a drinking glass next to his nightstand. On the glass, just one set of fingerprints: Stacey Castor's.
The felony complaint against Stacey Castor says police found a turkey baster in the garbage pail in the kitchen of the home. On the tip of the baster, David Castor's DNA. In the tube, ethylene glycol.
The complaint also says Stacey Castor, in statements to police, “Acknowledged that from Friday evening and throughout (the) weekend (of his death two years ago), David Castor consumed large quantities of alcohol and spent most of his time in the bedroom alone consuming alcohol."
Castor also says she was the only person caring for her husband that August weekend in 2005.
David Castor's death, according to the sheriff, was made to look like a suicide. But investigators always thought otherwise. There was a Prestone anti-freeze container on the bedroom floor, the drinking glass with anti-freeze in it, only her prints on it, and the baster.
This weekend, NewsChannel 9 spoke briefly with David Castor's brother Gary. He said he's "numb." And like detectives, Gary said he knew his brother didn't take his own life, and yet he never thought it would play out like this.
Castor remains jailed without bail. She’s scheduled for a preliminary hearing this Wednesday in Clay town court.
