Solomon Pena, who authorities say was angry over his defeat and made baseless claims the election last November was "rigged" against him, was arrested on Monday evening just hours after SWAT officers took him into custody.

Albuquerque Police Chief Harold Medina described Pena as the "mastermind" of what he said appeared to be a politically motivated conspiracy leading to shootings at the homes of two county commissioners and two state legislators between early December and early January.

Pena, 39, ran unsuccessfully in November against incumbent state representative Miguel P Garcia, the longtime Democrat representing House District 14 in the South Valley. Garcia won by 48 percentage points, or roughly 3600 votes.

After the election, police said, Pena showed up uninvited at the elected officials' homes with what he claimed were documents proving he had won his race.

There was no evidence of widespread voter fraud in New Mexico in 2020 or 2022.

The shootings began shortly after those conversations.

"This type of radicalism is a threat to our nation and has made its way to our doorstep right here in Albuquerque, New Mexico," Mayor Tim Keller said.

"But I know we are going to push back, and we will not allow this to cross the threshold."

Four men conspired with Pena, who is accused of paying them cash to carry out at least two of the drive-by shootings in stolen vehicles, while Pena "pulled the trigger" during one of the crimes, Deputy Police Commander Kyle Hartsock said.

A lawyer for Pena who could comment on the allegations wasn't listed Monday night in jail records.

No one was injured in the shootings, which unfolded amid a rise in threats to members of Congress, school board members, election officials and other government workers around the nation.
