THE mother of a suspected gunman wrote a chilling letter about the nation's dangers before 18 people were killed in a mass shooting in Maine.
In a letter seen by The U.S. Sun and addressed to Maine lawmakers, Ruby Card voiced her opposition to lowering the voting age.
The letter has been unearthed as the hunt for Robert Card continues following Wednesday's shooting in Lewiston.
Senior citizen Ruby, from Bowdoin - located 15 miles from Lewiston - said: “16-year-olds are barely out of diapers.”
She raged: “They have not completed their formal education, perfected skills that would fit them for employment, and lack the maturity to logically think through a problem and arrive at [a] fact-based solution.”

Ruby claimed voting is a “right and duty” all knowledgeable people should exercise.
She alleged: “Teenagers lack the maturity and experience to do so.”
Ruby said that at 16, teenagers cannot sign up for the military or buy alcohol and cigarettes.
She branded the proposed bill “a purely politically endangered piece of legislation that endangers our state and our nation.”
Ruby urged that the Maine constitution shouldn't be amended without a thorough consideration of potential unintended consequences.
Card remains at large since two shootings erupted within four miles of each other on Wednesday evening.
One of the shootings happened at a bowling alley and the other took place at a bar.
Officials revealed 18 people have been killed, while 13 are injured.
Cops initially identified Card as a person of interest before he was later named a suspect.
There is an arrest warrant for eight counts of murder.

Cops have warned that the number of murder counts could rise as more victims are identified.
Police described Card as armed and dangerous as they released chilling footage of a man wielding an AR-15 stalking a bowling alley.
A flashlight and scope appeared to have been added to the AR-15 weapon.
Cops said the gunman stormed the Just-In-Time Recreation bowling alley just before 7 pm local time and opened fire.
One witness, known only as Brandon, told the Associated Press: "We were inside.
"Just a normal night of bowling and out of nowhere he just came in and there was a loud pop.
"Thought it was a balloon. I had my back turned to the door. As soon as I turned and saw that it was not a balloon, he was holding a weapon.
"I just booked it down the lane and I slid basically into where the pins are and climbed up to the machine and was on top of the machines for about 10 minutes until the cops got there."
Card then traveled to Schemengees Bar and Grille minutes later and opened fire, per cops.
Police said the weapon used in the shootings was bought legally earlier this year.
Hundreds of cops are involved in the search and a swarm of armored vehicles swooped on a home in Bowdoin.
They urged Card to leave the property before they were seen leaving the scene.
Cops have since extended their search out to sea after it emerged that Card owns a boat.
Divers are also set to search the Androscoggin River as part of their probe.
As part of the hunt for Card, cops told ABC that they found a note at his home.
They revealed that it is being described as a suicide letter addressed to his son.
Law enforcement previously revealed that Card was a certified firearms holder.
Card has previously been accused of threatening to carry out a shooting at a National Guard base in Saco, Maine.
Cops also said that Card had said he previously heard voices.
A U.S. official, who wished to remain anonymous, told The Associated Press that Card had been evaluated for erratic behavior in July, per the Lewiston Sun Journal.
Katie Card, the suspect’s sister-in-law, told NBC: “He was picking up voices that he had never heard.
“His mind was twisting them around. He was humiliated by the things that he thought were being said.”
Military records seen by NBC have revealed that Card enrolled in the Army Reserve in 2002.
He had no combat developments.
