Malik Faisal Akram, a 44-year-old British citizen, took four people hostage at a Texas synagogue in a 10-hour standoff that ended in his death. Akram entered the United States as a tourist about two weeks earlier and spent time in Dallas-area homeless shelters before Saturday’s attack at Congregation Beth Israel, in the suburb of Colleyville.
Two British teenagers were arrested as part of the investigation on Sunday and later released without charge.
