After he was pulled over by New Mexico police, the suspect in the killings of four Muslim men in Albuquerque denied any connection to the crimes that shook the city and its small Muslim community – and told authorities he was so unnerved by the violence that he was driving to Houston to look for a new home, court documents said.

Charging documents released Wednesday revealed new details about the suspect, Muhammad Syed, 51, who has been charged in two of the slayings. Police have said they are gathering evidence in two additional cases before charges are filed. 

“This has been a tough week for our community, but we all pitched in to solve these crimes and protect a community that felt like it was under attack,” Albuquerque police Chief Harold Medina said. 

Police received multiple tips about the suspect and his vehicle that eventually led to his arrest, charging documents say. Syed, a native of Afghanistan who police say immigrated to the U.S. about five years ago, was taken into custody Monday after a traffic stop more than 100 miles away from his southeast Albuquerque home.

ALBUQUERQUE SLAYINGS:Police in New Mexico arrest suspect in string of killings of Muslim men

Who is Muhammad Syed? Suspect denies involvement 

Syed, a Sunni Muslim, was charged in two of the killings. He was charged in the death of Aftab Hussein on July 26 and Muhammad Afzaal Hussain on Aug. 1.

Albuquerque police believe the suspect killed the first victim while hiding in a bush near the victim’s vehicle, an arrest affidavit says. Police say the second victim may have been killed in a drive-by shooting. Investigators linked bullet casings from both crime scenes to guns owned by the suspect, court documents say. 

Charges in the first killing, of Mohammad Ahmadi on Nov. 7, and Friday’s fatal shooting of Naeem Hussain, haven’t been filed.
