Appeals in two Niagara County homicide cases were rejected last week by the Appellate Division of State Supreme Court in Rochester.
The four-judge panel unanimously dismissed claims by the defendants that they didn't know what they were doing when they waived their rights to appeal as they pleaded guilty.
Anthony N. Adams, now 21, is serving a 40-year sentence for first-degree manslaughter and first-degree robbery.
During the summer of 2007, when he was 16, he robbed four Niagara Falls cab drivers, shooting two and killing one, Thomas Zacher, 55. Adams, who pleaded guilty in April 2008, is in Southport Correctional Facility, Chemung County.
Randy Colucci Sr. and his wife, Nicole L. Colucci, are serving three to nine years for second-degree manslaughter in the asphyxiation death of their 22-month-old daughter, Carmen Colucci.
She tried to climb out of her playpen in the couple's Niagara Falls home March 30, 2010, but got her neck caught between the playpen's top rail and a mattress, weighed down by a TV set, which the parents had placed atop the playpen to prevent her from getting out.
Randy Colucci, now 27, was transferred from a prison to a mental institution last August, four months after sentencing. Nicole, now 26, is in Albion Correctional Facility. The earliest parole date for both is February 2014.
