Law enforcement officers in Maine are in the midst of a massive manhunt for the suspected gunman responsible for mass shootings that killed 18 people and injured 13 more.

The shootings took place at two different locations in Lewiston, Maine, on Thursday night, according to police. The suspect has been on the run ever since.

Here is how the mass shootings unfolded:

The bowling alley where the shooting took place posts on Facebook that it is "devastated" for the community and the staff.

"We lost some amazing and whole hearted people from our bowling family and community last night," the post on Just-In-Time Recreation's Facebook page read. "There are no words to fix this or make it better."

Around 9:30 a.m.

Maine Gov. Janet Mills tells reporters during a news conference the death toll from the shooting is now 18 people, with another 13 people injured.

Card has since been charged with eight counts of murder, Ross said, adding that the number of counts will ultimately be 18 once the remaining victims are identified.

He should be considered "extremely" armed and dangerous and should not be approached, Ross said.
