Peterson Was Tailed by Up to 6 Unmarked Cars

Police had up to six unmarked cars following Scott Peterson each day for weeks after his pregnant wife vanished, according to testimony Thursday at his double-murder trial.

Prosecutors are attempting to show that Peterson drove erratically and acted oddly as authorities scoured San Francisco Bay for his wife’s body in early January 2003, even suggesting he made three trips to a marina there because he was worried police would discover her remains.

Defense lawyers, however, said Peterson made the trips simply out of concern for his wife, and that he drove erratically because Peterson thought he was being tailed by reporters.
