ALBUQUERQUE, N.M. (AP) — A fear of attacks that had rippled through Muslim communities nationwide after the fatal shootings of four Muslim men in Albuquerque gave way to shock and sadness when it turned out the suspect in the killings is one of their own. Muhammad Syed, 51, was arrested late Monday after a traffic stop more than 100 miles (160 kilometers) from his Albuquerque home. The Afghan immigrant denied any connection to the crimes that shook the city and its small Muslim community. In court documents, in fact, he told police that he was so unnerved by the slayings that he was driving to Houston to find a new home for his family, which includes six children. But investigators said they have ample evidence to prove his guilt, though they have yet to uncover the motive for the ambush-style killings, the first of which was in November and then three between July 26 and last Friday.
