seconds. good evening. we have breaking news as we come on the air tonight.

john targeted in a u.s. armed drone strike earlier today. the knife-wielding masked man became a symbol of isis after authorities believe he beheaded a number of hostages. joining us now with late-breaking details is abc's chief investigative correspondent brian ross. >> good evening, juju. he was the face of evil and the u.s. has been tracking and targeting jihadi john, a british citizen, for months. u.s. officials say the air strike thursday was launched by a drone as the target left a building in raqqa, syria, then entered a vehicle. one official told abc news it was a 100% flawless direct hit. the world first came to know jihadi john a little over a year ago when he appeared in this video wearing a black mask, holding a knife, threatening the life of american journalist james foley. his voice was disguised but he could not hide his british accent. >> you've plotted against us and gone out of your way to

>> reporter: one after the other he presided over the murders of foley, american steven sotloff, two britons, two japanese hostages. >> our knife will continue to strike the necks of your people. >> reporter: earlier this year, his true identity was revealed to be mohammad emwazi, seen wearing an american baseball cap. the son of kuwaiti emigrants to the united kingdom. emwazi was spotted by his teachers as having a violent streak. one teacher told the bbc at age 11 he was put in anger management therapy. >> we'd find that he'd get very angry and worked up. it would take him a long time to calm himself down. >> reporter: flaunting his role as executioner once he joined isis with his piercing eyes and gravelly voice, emwazi became one of the world's most wanted men. in a statement to abc news the parents of murdered hostage james foley said the air strike against jihadi john was small solace.

"this huge effort to go after this deranged man filled with hate, when they can't make half that effort to save the hostages while these young americans were still alive. it's unfortunate that the government doesn't get it. they think it gives us solace but it doesn't." u.s. officials say they presume emwazi was killed in the drone strike based on what they observed of the hit. the vehicle he was in burst into flames and one official said jihadi john essentially evaporated. >> brian, could this be a turning point in the battle against isis? >> certainly the u.s. hopes so and it will give the isis leaders there pause about how effective the u.s. was in tracking down this one top target. well? >> our thanks to you, brian, for staying on top of the story over a year. we'll have complete coverage on "gma" first thing in the morning and online with the latest 24/7 at abcnews.com. mystery. a young pastor comes home to find his pregnant wife shot in their home.

she is endlessly surprising, remembering the turmoil of her own childhood. she says she was dramatic, filled with so much volatile feeling, her brothers called her nitro. >> i didn't know that i was an actor, i just knew that i was -- weird. different. i knew that i was smart but the evidence just didn't agree. >> didn't people think you were adhd? >> oh, yeah, i was everything. i would think something and then feel it. now i know what that is. now i can channel that at work. you don't know why somebody's telling a story then you're sobbing. it just makes you look like you're trying to get all the attention. >> reporter: in desperation her parents agreed to let her 14-year-old daughter come to new york and try her luck. she and her mother had only been here a few days when a photographer walked up to the girl, standing at a crowd in union square. >> my mom gave him her number. we didn't know that that was potentially dangerous and creepy.
