Law enforcement officials in New Mexico identified 51-year-old Muhammad Syed as the primary suspect in a string of killings of Muslim men in Albuquerque over the past nine months. 

Syed, who is originally from Afghanistan, was arrested on Monday evening and will be charged in two of the murders for allegedly shooting and killing 41-year-old Aftab Hussein on July 26 and 27-year-iold Muhammad Afzaal Hussain on Aug. 1.

Albuquerque Police Chief Harold Medina Page said detectives are still investigating and working with the district attorney to determine whether charges will be filed for the two other murders, in which Syed is a suspect. 

Police arrested Syed after he left his home on Monday evening in a Volkswagen Jetta that authorities believe was used in two of the murders. His car and home were then searched. 

"Detectives discovered evidence that shows the offender knew the victims to some extent and an interpersonal conflict may have led to the shootings," the Albuquerque Police Department said on Tuesday.

The gun that was used in at least two of the murders was also found in Syed's home, police said. 

When a reporter asked at Tuesday’s press conference if Syed, a Sunni Muslim, could have been motivated by anger that his daughter married a Shiite Muslim, Albuquerque Police Deputy Commander Kyle Hartsock said that "the motives are still being explored fully to understand what they are."

"We do have some information about those events taking place, but we're not really clear if that was the actual motive, or if it was part of a motive, or if there's just a bigger picture that we're missing," Hartsock said.
