ALBUQUERQUE, N.M. (AP) — An Afghan refugee convicted of first-degree murder in one of three fatal shootings in 2022 that shook Albuquerque’s Muslim community pleaded no contest Tuesday to two homicide charges stemming from the other killings.

Prosecutors said Muhammad Syed, 53, entered the pleas to two counts of second-degree murder for the deaths of Muhammad Afzaal Hussain, 27, and Naeem Hussain.

A jury had convicted Syed in March in the shooting death of Aftab Hussein, 41, in July 2022.

The three ambush-style killings happened over the course of several days, leaving authorities scrambling to determine if race or religion might have been behind the shootings. Investigators soon shifted away from possible hate crimes to what prosecutors called the “willful and very deliberate” actions of another member of the Muslim community.

Syed, who settled in the U.S. with his family several years earlier, denied involvement in the killings after being stopped more than 100 miles (160 kilometers) from Albuquerque. He told authorities he was on his way to Texas to find a new home for his family, saying he was concerned about the killings in Albuquerque.

Bernalillo County prosecutors say Syed faces a life prison sentence in Aftab Hussein’s killings and will serve 30 years behind bars for the no-contest pleas. A sentencing date hasn’t been set.

Authorities said Afzaal Hussain, an urban planner, was gunned down Aug. 1, 2022, while taking his evening walk. Naeem Hussain was shot four days later as he sat in his vehicle outside a refugee resettlement agency on the city’s south side. Aftab Hussein was a student leader at the University of New Mexico who was active in politics and later worked for the city of Española.

After Syed’s conviction in March, prosecutors acknowledged that no testimony during the trial nor any court filings addressed a possible motive. Prosecutors had described him as having a violent history, but his public defenders argued that previous allegations of domestic violence never resulted in convictions.
