After days bolstering security around Albuquerque-area mosques, seeking to allay fears of a shooter driven by anti-Muslim hate, police said on Tuesday they had arrested 51-year-old Muhammad Syed, one among the city’s Islamic immigrant community.
Authorities said the killings may have been rooted in a personal grudge, possibly with intra-Muslim sectarian overtones.
All four victims were of Afghan or Pakistani descent. One was killed in November, and the other three in the last two weeks.
A search of the suspect’s Albuquerque home uncovered “evidence that shows the offender knew the victims to some extent, and an inter-personal conflict may have led to the shootings,” police said in a statement announcing the arrest.
Investigators are still piecing together motives for the killings of the four men, Deputy Commander Kyle Hartsock of the Albuquerque Police Department said at a news conference.
In response to reporters’ questions, Hartsock said sectarian animus by the suspect toward his fellow Muslim victims may have played a role in the violence. “But we’re not really clear if that was the actual motive, or if it was part of a motive, or if there is just a bigger picture that we’re missing,” he said.
Syed has a record of criminal misdemeanours in the United States, including a case of domestic violence, over the last three or four years, Hartsock said.
Police credited scores of tips from the public in helping investigators locate a car that detectives believed was used in at least one of the killings and ultimately track down the man they called their “primary suspect” in all four slayings.
