“Mommy put something in Daddy’s drink,” the 4-year-old told a babysitter after one incident, prosecutors allege.
NBC News said Matthew Burke drank from a glass of wine and a glass of soda on two separate occasions but spit the drink out after noticing a strange taste and odor.
He called police on Sept. 10 to report his suspicions, the network reported. Investigators took the drinks for testing and asked Matthew Burke to install a surveillance system inside his home.
The cameras recorded Renee Burke inside the apartment two days later. Sini said the footage of that final incident showed the couple's daughter holding baby bottles filled with antifreeze for her mother as Renee Burke poured the chemical into a wine bottle.
"When questioned by police, the defendant claimed she poured fruit juice into the victim's wine bottle to water it down," Sini said.
Detectives recovered multiple beverage bottles from Matthew Burke's apartment that, when tested, showed the presence of ethylene glycol, a chemical in antifreeze that is deadly when ingested, according to the district attorney.
Sini said a search warrant for Renee Burke's home turned up a bottle of pink-colored Prestone antifreeze. Investigators also searched Renee Burke's cellphone, on which they found searches for "antifreeze with alcohol," "what liquids for cars can kill a human" and "can antifreeze kill a human," the district attorney said.
“The evidence in this case is strong and we will prosecute this dangerous individual to the fullest extent of the law,” Sini said.
Renee Burke was booked into the Suffolk County Jail, from which she was released after posting bond. If convicted of the attempted murder charge, she faces up to 25 years in prison.
A judge issued an order of protection Thursday banning the defendant from having contact with her children.
She wrote on her Facebook page Thursday that she'd had "an eventful day."
"I have spent the entire day being reminded that evil and lies never win," she wrote. "I have once again been reminded that if you have faith in God, he will never let you down even when it seems like there is no hope. I want to remind my friends and family that I love them with all my heart and my children are my life and (I) will pray that they will one day understand that they never have to be afraid to tell the truth."
Matthew Burke’s attorney, Rick Stafford, said his client is grateful the charges have been filed.
"He feels he can sleep at night now," Stafford told Newsday.
