LEWISTON, MAINE - The mass murderer in Maine wrote a note to a loved one with his phone's passcode and bank account before he was found dead about a mile away from his abandoned car.

Robert Card indiscriminately opened fire with a semi-automatic rifle inside a bowling alley and bar in Lewiston, Maine, on Wednesday, killing at least 18 people and injuring 13 more. 

Maine Public Safety Commissioner Mike Sauschuck said the paper note he left behind wasn't "an explicit suicide note, but the tone and tenor was that the individual was not going to be around."

Two nights after the shooting - around 7:45 p.m. Friday - law enforcement found Card dead from a self-inflicted gunshot wound inside one of about 55 to 60 metal trailers in a recycling center's overflow parking lot.

His body and two guns were found inside one of the unlocked trailers, which are essentially long, rectangular metal boxes packed with waste and other garbage in the recycling center's overflow lot, Sauschuck said on Saturday.

An ATF agent said Card legally purchased all the recovered guns "somewhat recently."

The lot where Card was found is separated from the main facility by a street and is northwest and out of the way from the main building, Sauschuck said, so police didn't search the trailers after they cleared the facility twice before.

"We're not just talking about a small area. I'm talking large industrial park," said Libson Police Chief Ryan McGee, who was one of the first officers on scene when they found Card's body.

But the "diligent" owner of the facility sent another tip to law enforcement about these trailers in a lot across Capitol Avenue, which is considered the recycling center's property, and prompted a law enforcement third visit - and the first to this lot, Sauschuck said.

"So then the follow-up is with the tactical team commanders to say, okay, tell me exactly where they are," said Sauschuck, referring to his conversation with the business owner.

"We didn't clear those. Let's go back. So the Maine State Police tactical team ultimately were the ones that located the body within one of those trailers."

Exactly when Card died is still under investigation, and that could take time, Sauschuck said. 

The location of the overflow lot is along a direct route that runs along the Androscoggin River and is less than a mile away from where law enforcement found Card's abandoned Subaru at a boat launch.

The owner's tip was one of more than 820 tips and leads law enforcement received since Wednesday's shooting.

Police chased down every potential lead and treated the tip as if Card would be there and responded in force, including armored trucks and heavily armed law enforcement officers.

Fox News Digital followed police and watched several searches from a handful of these tips.

One was a potential sighting that ended up being a man with a similar look just getting his mail. Another ended up being construction noise behind a business. 

One resident on a dead end street told Fox News Digital that he called police to tell them he owns an unlocked, detached shed and small building on property across the street from his home that is accessible from the abandoned car.

"I wanted to make sure no one was inside any of my properties before I locked it up," the owner told Fox News Digital on Friday.

He wanted to remain anonymous because Card was still considered to be on the loose at that time.

Remembering the victims

Law enforcement held several press briefings Thursday, Friday and Saturday.

Throughout the briefings, the victims were always present.

Pictures and their names were on a screen behind Sauschuck. If he, or the speaker, needed to show a graphic or map, they switched it back to the victims' pictures. 

Of the 13 injured, three remain in critical condition, Sauschuck said Saturday morning.

Counseling for victims who suffered physical injuries or were traumatized is set up in a private setting. The city is also offering help for anyone in area who has been impacted.

"(Card) is dead. We Know where he's located," Sauschuck said. "We can start working with our victims."

And he said that includes Card's family. At least three of family members were the first people to ID Card, he said.

"Realistically, right now we should only be really thinking about the victims," he said Saturday morning. "That's also the suspect's family as well.They were very forthcoming to law enforcement."

Fox News Digital attempted to speak to family multiple times, but they declined all comments.
