KANSAS CITY (NBC) - Are you tweeting right now?

Better be careful because a tweet about your whereabouts could leave you vulnerable.

Lots of us tweet to let friends know where we are but that may be a very public invitation for trouble.

All it took was this one tweet and 140 characters to let the world know that Israel Hyman and his family were in Kansas City and more importantly that they were not home.

"It's pretty unnerving. You worry, could this happen again?" asked robbery victim jerry Hyman.

Israel's father Jerry stopped by his son's home while they were away and found that someone had broken in.

Israel later tweeted that the thief or thieves stole Israel's Mac pro computer, two displays, and printer.

The family is not sure if it was because of Hyman's tweet.

"We don't know for sure if that's what caused the break it in, but it sure gives you pause to think about what you're publicly going to broadcast on the internet," said Hyman.

Tech analyst Rob Enderle says you can't get too personal on social networking sites like Facebook and Twitter.

It's just downright risky.

"There's just certain things you need to be very careful with. The advertising and any social network that you're going to be away is just asking to be burglarized," said Enderle.

It didn't take that long to find people weren't home on Twitter and Facebook.

This user was at the Orpheum Theater and another was at a restaurant eating hot dogs.

Alejandro Adams says he's not worried about people knowing he's not at home.

He says he tweets to let people know when his film company is on location.

"Without proof it's just sort of alarmism. You can't say he shouldn't have said he was going on vacation because some criminal was following him on twitter," said Adams.

But Facebook user Donna Berry says she's going to stop posting her vacations.

"I don't think I will be mentioning when or where. Having your house broken into is definitely worrisome," Berry said.

Police in Arizona say they are not 100 percent sure if the tweet is what led to the burglary.

Israel Hyman says he will continue to tweet, but from now on, he says he will be more careful about the information he shares.
