Monday marks one week since 5-year-old Dulce Maria Alavez suddenly vanished at a New Jersey park, prompting an Amber Alert and a massive manhunt as her devastated family waits for answers.
Dulce was last seen just before 5 p.m. EST on Monday, Sept. 16, while playing at the Bridgeton City Park behind Bridgeton High School.
It's possible the 5-year-old left the park with an unknown man and was lured into a van or SUV, authorities said.

"She's only an innocent child, who likes to have fun and play games," he said. "We don't [know] why she's disappeared."

The images may seem unimportant but could be a "valuable piece of the puzzle in helping us bring Dulce home," the prosecutor said.
