CHULA VISTA (CNS) - A sex offender who attacked two women and two teenage girls in National City and Chula Vista over a two-day period last year was convicted Thursday of seven felony charges, including kidnapping for robbery.

Leonard Earl Scroggins faces 165 years to life in prison when he is sentenced Jan. 24 by Judge George "Woody" Clarke.

During their second day of deliberations, jurors found the 34-year-old defendant guilty of committing a forcible lewd act on a child with a knife, attempted kidnapping for the purposes of a lewd act, assault with a deadly weapon, robbery, kidnapping for robbery with a knife and two counts of attempted robbery.

Scroggins also admitted a 1994 rape-in-concert conviction from Napa County and a 2004 criminal threats conviction that stemmed from a sexual assault in Alameda County, said prosecutor Enrique Camarena.

Scroggins was arrested at a South Bay park the night of May 19, 2010, after a car and foot chase.

The night before, Scroggins tried to rob a 17-year-old girl in the 500 block of Oxford Street in Chula Vista, police said.

Less than an hour later, a knife-wielding man matching Scroggins' description grabbed a woman in the 500 block of Anita Street and tried to pull her into a vehicle. The victim resisted and was stabbed in an arm before breaking free.

About 2:30 p.m. on May 19, 2010, Scroggins stole a young woman's purse near East 30th Street and B Avenue in National City and fled in a silver Nissan Quest, according to Camarena.

About 90 minutes later, a man grabbed a 13-year-old girl from behind and put a knife to her throat near Q Avenue and East 16th Street in National City. The girl, who suffered a cut finger in the assault, managed to elbow the aggressor and run to a relative's home.

The purse-snatching victim gave police a license number on the Nissan Quest, and National City detectives picked up Scroggins, who implicated himself in the earlier crimes in Chula Vista, authorities said.

Scroggins apparently traveled to the San Diego area after taking off a tracking device he had been ordered to wear by a Napa County judge due to his sex-offender status there.
