New Mexico police are investigating a possible link between the killing of 3 Muslims this year and the killing of another Muslim man last year, while calls for the condemnation of these crimes with racial motives are increasing.

Albuquerque police said - in a statement - that they found the body of a fourth dead person late on Friday.

Police did not identify the dead man, but said he was in his twenties and a Muslim of "South Asian origin".

"Investigators believe that this murder may be linked to three recent killings of Muslim men from South Asia as well," the statement added.

Among the victims were two Pakistanis, one of whom was 27 years old when his body was found on August 1, and the other was 41 when his body was found on July 26.

Police said investigators are looking into whether these murders are linked to the November 7, 2021 killing of an Afghan man in front of a business he runs with his brother in Albuquerque.

The police called on anyone with information to call a specific phone number, noting that the FBI is assisting in the investigation.

And Michelle Logan Grisham, Governor of New Mexico, expressed outrage at these attacks, and stressed her solidarity with the Muslim community in the southwestern United States.

"The targeted killings of Albuquerque Muslims are deeply outrageous and will never be tolerated," Grisham wrote on Twitter.

The Council on American-Islamic Relations (CAIR), the largest Muslim civil rights organization in the United States, announced on Saturday that it had offered a reward of $10,000 to anyone who provides information leading to the arrest of the suspect.

"This tragedy affects not only the Muslim community, but all Americans," said Nihad Awad, National Executive Director of the Council on American-Islamic Relations.

"We must unite against hatred and violence, regardless of the race, religion or origin of the victims and perpetrators," he added.
