US police found the body of suspect Robert Card, 40, with multiple gunshot wounds.
Initial assessment revealed that the suspect committed suicide with a gun. A source said the body of suspect Card was found near a recycling plant where he worked.
On the evening of October 25 (US time, morning of October 26), 18 people were killed and 13 others were injured in a mass shooting in the city of Lewiston, after which US authorities have launched a rigorous search for the suspected card.
The suspect, Card, holds the rank of sergeant in the U.S. Army Reserve in Saco City, a law enforcement official told the AP.

Earlier, the suspect was most wanted by US authorities after a series of shootings at restaurants and bowling alleys in the city of Lewiston.
The Androscoggin County Sheriff’s Office later posted a photo on Facebook of the suspect holding an AR-15 style rifle.
Suspect Card was admitted to a mental health facility for two weeks last summer. Family members of the suspect said that voices kept roaming in his mind and he felt that everyone around him was against him.
The suspect also recently broke up with his long-term girlfriend and investigators are focusing on the theory that the suspect went to the bowling alley and Schemanzi’s restaurant because these are places the couple frequents.
Investigators believe Card’s ex-girlfriend had signed up for a contest at the restaurant on the evening of the attack.
Suspect Robert Card’s motive for the shooting is still under investigation.
