As the story of three formerly missing women in Cleveland develops Tuesday, the city's Department of Public Safety is encouraging journalists to use Twitter to get credentialed for a press conference this morning.


(DM means "direct message," a way of communicating privately on Twitter.)

Reached by email, Cleveland DPS communications planner Erica Creech says she's the person behind the @CLESafety account and that this is the first time the department has used Twitter in this way.

"We were short staffed and I was trying to keep up with all the additions to our distribution list but wanted to get info out so I gave it a shot...seems to work so long as you can then keep up with Twitter," she writes. "Since I can more easily access Twitter via mobile devices, it is always messages are shorter, so less typing."

The DPS has a useful blog, too, with updates Monday about the women's discovery and three suspects' arrests.
