Transcript for US Confirms American Journalist Executed in Video
execution of another American journalist. Authorities confirm overnight that video is Steven sotloff being murdered by an Isis militant. ABC's Brian Ross is here with the latest. Reporter: Good morning. As you say U.S. Authorities have confirmed the gruesome video is authentic as president Obama vowed that Isis will pay the price for the murder of a second American journalist. The president delivered fighting words this morning as he said Isis will achieve nothing by the barbaric murders of Steven sotloff and James Foley. We will not be intimidated. Their horrific acts only unite us as a country and stiffen our resolve to take the fight against these terrorists. Reporter: U.s. Officials say sotloff never had a chance in the hands of the brutal Isis group despite an emotional plea for mercy from his mother. I ask you to please release my child. Reporter: British authorities this morning said the hooded executioner appears to be the same british accented speaker who two weeks ago beheaded journalist James Foley. Investigators are already comparing the voices from the two Isis videos along with an analysis of the desert setting, the speaker's use of his left hand to hold the knife and his eyes. Earlier U.S. Facial recognition experts had created this Li likeness from an examination of the eyes and the president this morning vowed to find whoever was responsible. And those who make the mistake of harming Americans will learn that we will not forget and that our reach is long and that justice will be served. Reporter: At the end of the sotloff video Isis produced yet another western hostage, identified as a british citizen named David Haynes threatening to do the same to him and U.S. Officials say there are at least two more Americans being held by Isis, two young aid workers who had gone to Syria to help civilians caught in the middle of the strife.
