A mother who rolled over and asphyxiated her baby while sleeping from a mix of marijuana and prescription medications pleaded guilty and asked for leniency in a New York State court last week.
"I carry the ultimate punishment," Danielle Lefay said in a Broome County court Friday. "I am deeply sorry for being the one to neglectfully... take her last breath."
The previous January, Lefay, 41, was sleeping on an improperly inflated air mattress beside her 6-month-old daughter Vianna when it collapsed as the two slept.
Vianna was smothered to death. In March, a grand jury indicted Lefay for felony counts of second-degree manslaughter and criminally negligent homicide.
Lefay's roommates found the little girl unresponsive in the apartment the next day. Paramedics responded and administered CPR, but Vianna was pronounced dead at a hospital.
Last week, Lefay admitted that a combination of her drug use and lack of understanding of the risks she was posing to the baby resulted in the girl's death.
Lefay's plea agreement allows the judge to impose jail time served, probation, or up to three years in state prison, according to the Press & Sun Bulletin.
Lefay's sentencing hearing is scheduled for January 20.
