TOLEDO (WTOL) - A man connected to an alleged domestic terror plot in Toledo appeared in court on Wednesday.

Vincent Armstrong, 23, was charged with making false statements to law enforcement officials during an investigation into himself and his girlfriend Elizabeth Lecron.

Officials deemed that he is a danger to the public and should not be released during the investigation into his part of the alleged plot.

Lecron is accused of planning a mass killing at a Toledo bar and purchasing materials to make a bomb for use in a domestic terrorist attack, the FBI says.

Lecron apparently was active on social media and glorified mass murders such as the Columbine gunmen and the mass shooting of churches.

Armstrong, who lived with Lecron, was said to have changed his behavior dramatically when he began dating Lecron. He began wearing camouflage, went to the shooting range with Lecron, and expressed an interest in a mass killing.

The two even traveled in August to visit sites related to the shooting at Columbine High School.

Police also found an AK-47, shotgun, multiple handguns, ammunition and end caps purchased by Armstrong. End caps can be used in the manufacture of pipe bombs, in a search of their residence and vehicles.

They also found journal entries from the two discussing violent attacks.

Armstrong denied discussing plans with Lecron to launch an attack and denied purchasing items that could be used to make a bomb when interviewed by police on Monday.

Armstrong’s family was in the courtroom and said they are shocked and saddened, and can’t believe he would be involved in any violent plots.

Now, Vincent Armstrong's case will be heard by a federal grand jury.

He and Elizabeth Lecron are both being held at the Lucas County Jail.

The investigation into Armstrong’s involvement into the alleged plot is ongoing.
