It’s not uncommon for first responders in the area to send crews to other cities or counties in the case of an emergency.

You may remember that in January the Olathe Police Department sent a bomb squad and the Shawnee Police Department send a K9 unit to Lawrence when a suspicious box and message were found at the Douglas County Courthouse.

On Monday, Lawrence-Douglas County Fire Medical returned the favor when a massive fire broke out at an Overland Park apartment complex and the city’s fire department needed help.

The Associated Press reports that the fire began at the multimillion-dollar CityPlace development in Overland Park before spreading to nearby homes.

In all, 22 houses were damaged, some significantly so, and 100 firefighters were called to fight the flames until late Monday afternoon, when the fire came under control.

LDCFM Division Chief Eve Tolefree said in an email that a total of 11 members of the department responded to the Overland Park Fire Department’s request for mutual aid.

“Out units stood by in a designated staging area in preparation to support fire suppression activities,” she said.

Ultimately three firefighters were treated for minor injuries. However, Tolefree said the 11 members of LDCFM were not among the wounded.

All LDCFM members returned home Monday night, Tolefree said.

Some crews were checking the scene for hot spots on Tuesday, but Tolefree said Lawrence and Douglas County crews were not involved in the cleanup phase.
