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.

A note for a loved one was discovered in Robert Card's residence in which he left phone passcodes, bank account numbers and more. Investigators are working on accessing his phone and bank information through search warrants.
Police emphasized that the family has been highly cooperative. Sauschuck believes the first three individuals who positively identified the gunman based on released photos were family members.
On speculation about Card's mental health, Sauschuck stressed that "the vast majority of people with a mental health diagnosis will never hurt anybody. They won't hurt themselves. They're not a danger to the community."
He added that while a mental health component could play a role, there is still more research to be done. Sauschuck has not seen evidence that Card was “forcibly committed for treatment" regarding mental health.

The U.S. Coast Guard is searching the Kennebec River in Maine for any sign of the mass shooting suspect, Robert Card.
Card owns a boat and property in the Lewiston area, according to a source briefed on the situation.
"Currently, one response boat crew from Station Boothbay Harbor, and an Air Station Cape Cod HC-144 fixed wing aircraft are assisting with patrols," Coast Guard spokesperson Rob Simpson said in a statement.
Maine mass shooting suspect Robert Card allegedly behaved erratically this summer while serving as an Army reservist, according to a defense official.
Card was deployed to Camp Smith Training Center in upstate New York to help support summer training for West Point cadets.
Card allegedly threatened other soldiers with violence, according to a source briefed on the situation.
"Out of concern for his safety, the unit requested that law enforcement be contacted," the defense official said. Police took Card to Keller Army Community Hospital at the United States Military Academy for a medical evaluation, the official said.
Sometimes this spring or summer, Card bought an accessory to a firearm, according to the source briefed on the situation.
With the manhunt for Card ongoing, the source noted that Card owns a boat and property in the Lewiston area.

A sweeping dragnet effort is underway on the ground and in the air as law enforcement partners fan out in full force in their search for the suspected Lewiston gunman, Robert Card.
More than 350 law enforcement personnel are involved in the search.
Evidence response teams are already on the ground, processing the "very extensive scenes" where the shootings took place, FBI Special Agent in Charge Jodi Cohen said.
In these early stages, investigators are probing potential mental health issues Card may have had, and how he was in possession of a weapon.
A motive has also not been determined.
"I think those are all valid questions and certainly questions that we are looking into now, but not questions that we can answer today," Commissioner of Maine's Department of Public Safety Mike Sauschuck said.

President Joe Biden said in a statement Thursday, "Once again, our nation is in mourning after yet another senseless and tragic mass shooting."
He said he's "praying for the Americans who’ve lost their lives, for those still in critical care, and for the families, survivors, and community members enduring shock and grief."
"Far too many Americans have now had a family member killed or injured as a result of gun violence. That is not normal, and we cannot accept it," Biden said.
He said, while the nation has made progress on gun reform with "the Bipartisan Safer Communities Act, the two dozen executive actions I’ve taken, and the establishment of the first-ever White House Office of Gun Violence Prevention, it’s simply not enough."
Biden said he's urging Republicans in Congress to "work with us to pass a bill banning assault weapons and high-capacity magazines, to enact universal background checks, to require safe storage of guns, and end immunity from liability for gun manufacturers."
"This is the very least we owe every American who will now bear the scars -- physical and mental -- of this latest attack," he said.
"Last night, Lewiston became yet another community torn apart by senseless gun violence," Vice President Kamala Harris added on Thursday.
Harris, speaking at a State Department luncheon as part of the Australian prime minister's visit to Washington, D.C., noted how Australia enacted transformative gun reform after a 1996 mass shooting, banning semi-automatic and other weapons. Gun-related deaths in Australia then dropped significantly.
"The leading cause of death of American children is gun violence," Harris said. "Gun violence has terrorized and traumatized so many of our communities in this country. And let us be clear, it does not have to be this way, as our friends in Australia have demonstrated."
Biden received another briefing on the shooting Thursday morning and has ordered the U.S. flag to be flown at half-staff at the White House and all public buildings and grounds, according to the White House.
