Scott Peterson is back in the news more than 15 years after the death of his wife and unborn son in a murder for which he was convicted in 2004.

As CrimeOnline reported last week, Peterson’s defense attorneys have continued to argue evidence that could potentially exonerate him was withheld from presentation during a trial that ended with a conviction and death sentence.

Police officers arrested Peterson the day after his wife’s body was found in 2003. At that time, the 30-year-old suspect claimed he was meeting relatives to play golf.

Reports indicate he was carrying $15,000 in cash, hundreds of sleeping pills, about 10 Viagra pills, multiple cellphones and an identification card belonging to his brother. He was also found in possession of weapons including a firearm and a dagger.
