NEW BRUNSWICK, N.J. (AP) — A New Jersey man has admitted he suffocated his mother to death during the Thanksgiving holiday weekend.

Frank Polera on Monday pleaded guilty to aggravated manslaughter in the death of 61-year-old Patricia Polera in November 2016 in the Old Bridge home that they shared. An autopsy showed she had died from asphyxiation by compression.

Under terms of a plea agreement, the 31-year-old will be sentenced to up to 28 years in prison.
