Debra Aquilina, of Garfield, N.J., insisted at her Friday sentencing she didn't kill her husband.

Prosecutors said the 51-year-old Aquilina conspired with her son to kill 45-year-old Ralph Ludvik Jr. so she could take title to his house. She had married him six months earlier.

The death initially was ruled an accidental heroin overdose. But authorities reopened the investigation after a tip from a jailhouse informant.

Aquilina's son was convicted previously and is serving a 44-year sentence.
