The husband of missing Laci Peterson was arrested in San Diego for the murder of his wife Friday evening, according to law enforcement sources.
Sources said Scott Peterson was arrested without incident and that police were aware of Peteron?s location for the past few days.
The arrest comes in the wake of two grisly discoveries last week, when the bodies of a baby boy and a pregnant woman were found in San Francisco bay.
Scientists have conducted DNA tests on both of those bodies and the results are expected to be released in a news conference at 9 p.m. EDT.
Law enforcement sources have told Fox News that, ever since the case first opened, they believed Peterson was responsible for the murder. They suspected him of throwing his wife's body into San Francisco Bay and securing it with concrete blocks, hooks and fishing weights.
Peterson has denied any role in the murder.
