Social media sites like Twitter and Facebook have played a big role in spreading information about the Boston blasts.
Police in central Wisconsin who use those sites say it's a good way to get information out quickly.
The Boston Police Department has used its Twitter page to answer questions and provide information. Officers there have been tweeting regularly since the attack using the Twitter handle @Boston_Police.
Police officers in central Wisconsin told Newsline 9 social media has become a very valuable tool, especially after a disaster.
"It's a different world that we live in now," said Kronenwetter Police Lt. Terry McHugh. He said social media sites are an easy way to connect with many members of the community in seconds.
"One of the nice things about Twitter or Facebook is it's real time information," he added.
Police officers in Wisconsin Rapids agreed.
"When we're using social media we're able to connect to a larger group of people who are interested in helping us out," said Lt. Brian Krzykowski.
The Wisconsin Rapids Police Department has more than 2,000 followers on Facebook.
"Especially when they start sharing the information with their friends as well, we're able to multiply the number of people we see," said Lt. Krzykowski.
However, officers say social media sites can also cause problems. It's easy to spread false information. That's why they recommend following verified accounts.
"It is a double-edged sword. Sometimes it's good and it provides good information, but sometimes it's bad," said Lt. McHugh.
Despite that, police officers said social media is valuable in solving crimes because they can receive tips and information easily.
Investigators in Boston hope they can get videos and pictures from the scene to find whoever is responsible for the explosions near the marathon's finish line.
