Law enforcement officers in Maine are in the midst of a massive manhunt for the suspected gunman responsible for mass shootings that killed 18 victims and injured 13 more.
The shootings took place at two different locations in Lewiston, Maine, on Wednesday night, according to police. The suspect has been on the run ever since.
Here is how the mass shootings unfolded:
Emergency dispatchers begin to receive 911 calls detailing a male shooting at Just-In-Time Recreation, a bowling alley in Lewiston, Maine, formerly known as Sparetime, State Police Col. William Ross told reporters during a news conference Thursday morning.
Law enforcement receives reports of an active shooter inside the billiards room at the Schemengees Bar & Grille restaurant in Lewiston, about 4 miles south of the bowling alley, Ross said.
Shortly after, a large law enforcement response from multiple surrounding agencies assists the Lewiston Police Department.
The Androscoggin County Sheriff's Office posts on its Facebook page that it's investigating two active shooter events.
The post includes a photo of the suspect brandishing a semi-automatic rifle.
Maine State Police posts on Facebook that there's an active shooter situation in the city of Lewiston, advising residents to shelter in place.
"Please stay inside your home with the doors locked," police said.
Law enforcement sources tell ABC News that a bowling alley in Lewiston is one of the scenes of the shooting.
There are additional reports of shots fired at the Schemengees Bar & Grille in Lewiston, the sources said.
A federal source also tells ABC News that there are multiple fatalities and the FBI is offering assistance.

Multiple sources tell ABC News that at least 16 people have died in the shooting. A massive manhunt for the suspect is in effect.
The FBI urges the public to remain vigilant and report any and all suspicious activity to law enforcement immediately.
The Gun Violence Archive, a database reporting on gun violence in the U.S., posts on X, formerly known as Twitter, that the Lewiston shooting is the worst to occur in 2023.
It was also the 565th mass shooting in 2023 and the 31st mass murder, according to the organization.
The Lewiston Police Department identifies a person of interest as 40-year-old Robert Card and releases his mugshot.
Card is considered armed and dangerous, police said.
Sources tell ABC News that Card has a history of military service as a firearms instructor and that he was treated at a mental health facility over the summer after he allegedly said he was hearing voices and threatened to shoot up a National Guard facility in Saco, Maine.
A vehicle registered to Card is located near a boat landing Lisbon, Ross said. The town is about about 8 miles southeast of Lewiston.
Police in nearby Lisbon advise residents to remain sheltering in place as the search for the suspect continues.
Maine State Police expands the shelter in place advisory and school closings to include the town of Bowdoin, about 15 miles east of Lewiston.
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."
Lisbon Police Chief Ryan McGee tells reporters that investigators are relying on the community's help to locate Card and that no tip is too small.
"If you see something in Lisbon that is suspicious, I want you to call," McGee said.
The flag on the roof of the White House is lowered to half-staff to honor the victims of the Maine shootings.

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.
The U.S. Coast Guard announces that it is searching the Kennebec River in Maine for any sign of Card.
Card owns a boat and property in the Lewiston area, according to a source briefed on the situation.
Multiple law enforcement sources tell ABC News that investigators recovered a firearm from Card's abandoned vehicle when it was found late Wednesday.
Authorities are testing and tracing the gun to determine if it was involved in the shooting.
The FBI searches a home in Bowdoin, Maine, associated with the suspect, federal sources tell ABC News.
Law enforcement surrounds the Bowdoin home, ordering Card to "come out now."
The search at the Bowdoin home winds down. Investigators do not believe Card will be apprehended at that location, a source familiar with the search tells ABC News.
The shelter-in-place order is rescinded, but hunting remains banned in four cities as the search for Card continues.
Card is found dead with a self-inflicted gunshot wound, multiple law enforcement sources told ABC News.
His body was found at a recycling center in Lisbon where he worked.
