RONKONKOMA - A day after John Grega was released from a Vermont prison after his murder conviction was overturned, he returned home to Long Island for the first time in 18 years.

John Grega was convicted of raping and killing his wife at a Vermont condo the couple was sharing in 1994. A jury sentenced him to life without parole.

However, DNA evidence recently cast a doubt on the conviction and a judge overturned the conviction and freed Grega on bail.

"I knew in my heart of hearts I wouldn't die in jail," says Grega. "I knew I was fighting a good fight. And when I got out of prison yesterday it felt so right, it felt like I just woke up from a dream and everything was right."

Grega says that it was his family that helped him get through his darkest days.

"They stopped living their lives to help me for 18 years, visiting me in Vermont four times a year through snow, sleet, car accidents," he says.
