SALT LAKE (HawaiiNewsNow) - As vehicles motor along Salt Lake Boulevard, and school lets out at Aliamanu Elementary, Jennifer Wolfe quizzes her seven-year-old daughter about safety.
"There's just so many kids that walk every day on every sidewalk around here. And they're all at risk," she said.
An alert from Honolulu Police warns parents about three recent incidents in the Salt Lake area involving dark blue vans.
In December, a man sitting in a blue van allegedly exposed himself to a 10-year-old girl. HPD said in January a male driving a blue van approached a 10-year-old boy and a 14-year-old girl in or near Navy housing. The latest incident was on Monday.
Aliamanu Elementary sent warning letters home to parents.
Mark Yang's 8-year-old daughter goes to school there.
"I got a little bit shocked because I thought Honolulu is a very peaceful place," said Yang, who recently moved into Salt Lake from Taiwan.
Forest City, the company that operates naval housing, wants families there to be vigilant. Wolfe said changes are visible.
"I've noticed more parents out watching their kids recently. Keeping a closer eye. Not letting them play in the front yard by themselves for a little while until we feel a little more comfortable," she said.
Yang is trying to make his daughter understand, without scaring her
"I just talked to her not to talk to a stranger, and wait in the classroom until I come," he said.
Police said none of the youngsters were abducted. More officers are patrolling the area.
"We hope the police can get the guy soon," Yang said.
