It happened in the 11000 block of Mile Drive in northwest Houston around 1:30pm Saturday.
It's a quiet neighborhood with a rural feeling.
"It's very concerning because this is the kind of neighborhood we know each other, a lot of us know each other," neighbor Sondra Sneed said.
"This is a cut through for a lot of traffic. So maybe it's one of those incidents where the people in the car saw the guy and said let's do it, hit and run and get the heck out. That's kind of bad," neighbor Dee Brown said.
On Saturday afternoon, U.S. Postal inspectors say a mail carrier was on their delivery route when approached by two men with guns and robbed of an unknown amount of money. They were seen driving away on Mile Drive toward North Eldridge.
"It just heightens it even more this time of year. Our carriers are very careful when they delivering. They know to watch their surroundings. We're just thinking that sometimes criminals like this take advantage of an opportunity," U.S. Postal Inspector Stephaine Harden said.
Neighbors along the dark road now are even more observant.
"We do have a very active neighborhood watch, and we have meetings once a month in the neighborhood. That description is something that definitely would be sent around," Sneed said.
And they say a crime in the middle of the day is even more troubling.
"I think we can band together and keep our eyes peeled more," Brown said.
Authorities are searching for two suspects between 20 and 25 years old. Both were described as about 5 feet 9 inches tall, thin and clean shaven.
They were seen driving a brown or green 2004 Toyota Corolla with Texas license plate JBZ900.
Anyone with information about the identity of the suspect is asked to contact authorities.
