UPDATE APRIL 12: People living in a neighborhood near Desert Inn Road and the 215 beltway say they've been victims of mailbox theft nearly a dozen times in the past year.
They're taking concerns all the way to Washington, D.C., with hopes to get newer, more secure cluster mailboxes.
Marie Salazar says she is home almost every day and she watches out her window for the thieves. She believes she's seen the person committing this federal crime.
She says he waits by the mailbox and takes the mail as soon as the mailman drops it off.
"All of a sudden it's gone after the mailman comes by," said Salazar.
Salazar and other neighbors want newer, more secure mailboxes so they've taken their concern to officials in Washington, D.C. for help. It could be months before those boxes are installed.
LAS VEGAS (KTNV) -- You could get thousand of dollars if you can help solve the latest crime wave in Summerlin.
The U.S. Postal Inspection Service is looking for a 35- to 45-year-old bald man in a white van who they said has been breaking into cluster mailboxes in Summerlin, near Sahara Avenue and the 215 beltway, and stealing the mail.
"Just be aware, pay attention to what's going on in your neighborhoods," said Andrea Avery, postal inspector. "If you see a suspicious person or suspicious vehicle near the mailboxes, call."
If you see someone stealing mail right then and there, call police. Otherwise call the United States Postal Service at 877-876-2455.
USPS is trying to find out more about the thief so they can get him to court. They are offering up to $10,000 for any information that helps track the thief down.
"The rewards are a case-by-case basis," said Avery. "Sometimes it's the amount of break-ins, sometimes it's just that we are frustrated and we need help to identify him."
Neighbors told 13 Action News they have already had checks and credit card information stolen, and they are pleased about the reward.
"It's about time they did something," said Alex Toth, who has lived in the affected neighborhood for 16 years. "It's a federal offense anyhow."
USPS said he has been hitting cluster mailboxes in the 89135 zip code, which covers Summerlin South.
