New Mexico Democrats' homes and offices have been targeted in 5 shootings in recent weeks

• Five shootings have targeted Democratic politicians' homes and offices in Albuquerque, New Mexico.
• Local and federal authorities are working to determine whether the attacks are connected and politically motivated.

Authorities are investigating five shootings that have targeted Democratic politicians' homes and offices in Albuquerque, New Mexico, in the past month.

No one has been injured in the shootings, and local and federal authorities are working to determine whether the attacks are connected.

"We're grateful that nobody has been injured, but we also realize that we have to move quickly," Albuquerque Police Chief Harold Medina said at a news conference on Thursday, adding that the attacks are a top priority.

He said that the police have evidence that they are processing and that no one was currently in custody in connection with the attacks.

The targets included residences and workplaces associated with the state's new attorney general, two state senators, and two county commissioners.

In the worst attack, the home of Commissioner Debbie O'Malley was riddled with more than a dozen gunshot impacts, Albuquerque police spokesman Gilbert Gallegos told NPR.

The first shooting took place on December 4, and the most recent one was on Thursday, according to authorities.

The Thursday attack involved three shots being fired near an office where state Sen. Antonio Maestas works. Maestas thanked the police for their work on Twitter and said that his family was "safe and sound."

Bernalillo County Commissioner Adriann Barboa, whose home was the first to be targeted, told NPR that it was difficult to process the attacks, "especially knowing that other women of color elected officials have also been targeted."

"We are worried and concerned that these are connected and possibly politically motivated or personally motivated, but we don't know that for a fact, so it's important not to speculate," Mayor Tim Keller said in the press conference.

Keller asked the public to help by reporting any suspicious activity they might witness around lawmakers' homes or workplaces.

Authorities said in the press conference that state police were involved in the investigation along with the FBI in Albuquerque.

While the attacks have not been proven to be ideologically motivated, lawmakers in the United States have been facing a rise in threats.
