Elias Abuelazam, 33, was arrested Wednesday night in Atlanta before a flight to his native Israel and charged with attempted murder in a July 27 knifing in Flint, Mich. Authorities said more charges are expected in Michigan, Ohio and Virginia. Abuelazam appeared at a brief court hearing in Atlanta on Friday morning, without an attorney, the Associated Press reported. He initially told Judge Richard Hicks that he wanted to stay in Georgia and face the charges, but Hicks told him that he would have to return to Michigan if he wanted to fight them. After Hicks explained the process further, Abuelazam agreed to waive an extradition fight, a process that could take months, and go back to Michigan, according to the AP. "All right, then I'll do so," he said. "It sounds more logical to go right now than in 90 days." The suspected "Flint serial killer" is a Christian from Israel who tried unsuccessfully to put down roots in Northern Virginia and once worked with troubled children at a Leesburg mental health facility, according to friends and court records. Elias Abuelazam, 33, married twice and tried to settle down in the region, first in Fairfax County and then in Leesburg. Both marriages ended in divorce, and after the last one in 2007, Abuelazam's life became more nomadic. He bounced between Loudoun County, Michigan, Florida and Israel, the friends and court records say. Nothing in Abuelazam's past could have predicted what authorities say he has done since May, the friends said. Over the past 11 weeks, Abuelazam began randomly stabbing and attacking men -- most of them black -- in Michigan, Virginia and Ohio, police say. About 10 p.m. Wednesday, U.S. Customs and Border Protection agents paged him over a loudspeaker at Hartsfield-Jackson Atlanta International Airport, where he was about to board Delta Flight 152 for Tel Aviv.
