Investigators believe one assailant likely is responsible for the three attacks against teenage women in the Eastlake Greens area, though the victims gave somewhat different descriptions of the man who grabbed and groped them, according to the Chula Vista Police Department.

The crimes took place within a roughly 2-mile radius of each other, CVPD spokesman Bernard Gonzales said.

The first assault occurred about 3:30 p.m. Saturday near the 1700 block of Winding Walk Street. The victim, a 16-year-old girl, said her attacker was a roughly 6-foot man who appeared to be in his early to mid-20s, weighing about 160 pounds with short blond hair.

The second crime -- the latest to come to light -- occurred in the same area as the first, roughly two hours later, Gonzales said. The 14-year-old victim was walking to a nearby mall when she encountered a youth with short blond hair resting his foot on a skateboard.

As she approached, the assailant blocked her way, pulled on her clothing and fondled her, then fled, Gonzales said. The victim described the attacker as 17 to 20 years old and weighing 150 to 160 pounds.

The third assault took place about 6:30 p.m. Monday in the 1100 block of Hunte Parkway, near Otay Lakes Road, the captain said.

The 18-year-old victim described the perpetrator as in his late teens, about 6 feet tall and 150 pounds, with collar-length blond hair.

The young woman said the man hit her with his skateboard when she fought to break free from his grasp.

In all three cases, the assailant was wearing shorts and a T-shirt.

Detectives are "working under the assumption" that the same man is responsible for each of the assaults, Gonzales said.
