Police had been searching for suspect Robert Card since Wednesday night.
The manhunt has ended for suspect Robert Card, who allegedly killed 18 people and injured 13 others in a mass shooting in Lewiston, Maine, on Wednesday evening. Gov. Janet Mills confirmed the suspect was found dead Friday night of an apparent self-inflicted gunshot wound.
Wednesday's mass shooting unfolded in two locations: a bowling alley where a children's league was taking place and a local bar, officials said.
The names of the 18 people killed in Wednesday night's mass shooting in Maine were released by authorities on Friday.
The victims at the bowling alley include youth bowling coach Bob Violette and his wife Lucille Violette, as well as bowling alley manager Tommy Conrad.
Aaron Young, 14, and his father William "Bill" Young, 43, were also among the victims at the bowling alley, their family said.
Victims Steven Vozzella and Bill Brackett were among those killed at Schemengees Bar & Grille Restaurant. They were a part of a gathering of deaf people playing cornhole.

There have been at least 565 mass shootings in the U.S. so far this year, according to the Gun Violence Archive. Mass shootings are defined as an incident in which four or more victims are shot or killed, according to the archive.
Wednesday night's mass shooting in Lewiston, Maine, which claimed at least 18 lives, is the deadliest shooting of the year and one of the deadliest in recent decades.
President Joe Biden in grieving the loss of life in Maine and is praying for the injured, White House national security spokesperson John Kirby told MSNBC.
Kirby urged Congress to do more to ban semi-automatic rifles, which he called weapons of war allowed on the streets, and said that Biden's recent legislation, the Safer Communities Act, was a start -- but not enough.
The Safer Communities Act included incentives for states to pass red flag laws, closed the so-called boyfriend loophole and created an enhanced background check process for people under 21 who are looking to buy firearms from licensed dealers. Biden himself, while signing the bill, said it wasn't everything he wanted but was a start.
Biden has ordered flags to be flown at half-staff in honor of the Maine victims.
White House response to latest mass shooting in Maine
Attorney General Merrick Garland said in a statement, "I am heartbroken for those who have lost loved ones, for those who have been injured, and for the entire Lewiston community."
"The FBI, ATF, and U.S. Marshals are on the ground to provide investigative support and victims assistance services to our law enforcement partners in Maine," he said. "No community should have to endure the horrific mass shootings that have become routine in our country."
The person of interest in the Maine mass shooting, Robert Card, has been an Army reservist since December 2002, the Army said.
He has no combat deployments, the Army said.
His current rank is sergeant first class. His job is listed as petroleum supply specialist.
The police chief in Lisbon, Maine, told reporters Thursday that no tip is too small in the hunt for Robert Carr, the person of interest in the Lewiston, Maine, mass shooting.

Lisbon borders Lewiston and is where authorities are searching for the person of interest.
The white Subaru believed to be linked to the person of interest was found in Lisbon.
"If you see something in Lisbon, that is suspicious, I want you to call," Chief Ryan McGee said.
The chief said that police had responses from agencies all across the state and their federal partners.
He said he sent every one of his available officers to the neighboring community before the situation came to Lisbon.
