SYRACUSE -- A jury of nine women and three men was seated Monday in the trial of a 41-year-old woman charged with poisoning her husband with antifreeze and later trying to kill her daughter and then concoct a suicide scenario blaming the daughter for the murder.

Stacey Castor, of Clay, faces a maximum of 25 years to life if convicted of second-degree murder in the death of her husband, David, in August 2005.

Castor also could face a consecutive sentence of 25 years if convicted of attempted second-degree murder for trying to kill her 20-year-old daughter, Ashley Wallace, in September 2007 with an overdose of drugs and vodka. Wallace was hospitalized several days but survived.

Lawyers said they were looking to seat jurors able to spend the next six to seven weeks in Onondaga County court. Prosecutors have said they could call as many as 50 witnesses, while Castor's attorneys have said they could have 15 to 20 witnesses.

Castor was charged with killing her 48-year-old husband last September. David Castor's death was initially ruled a suicide but investigators later determined he was poisoned with ethylene glycol, a toxic chemical found in antifreeze.

After David Castor's death, investigators in neighboring Cayuga County exhumed the body of Stacey Castor's first husband. Michael Wallace, 38, was initially thought to have died from a heart attack in 2000, but after the exhumation, authorities ruled his death a homicide caused by ingesting ethylene glycol.

Although Castor has not been charged with killing Michael Wallace, prosecutors said they plan to present evidence of Wallace's poisoning as proof Castor killed David Castor in a similar fashion.

The day Stacey Castor was charged, Ashley Wallace was rushed to the hospital in critical condition with a drug and alcohol overdose. After Wallace was hospitalized, investigators found a typed suicide note purportedly from her, confessing to the two murders. Prosecutors contend Castor typed the note to frame her daughter.
