Right now. Good evening. We begin with a potentially ominous turn in the investigation into the russian air disaster over egypt. A u. S. Official late today told nbc news that evidence indicates it was likeke a bomb, possibly planted by isis operatives that brought the airbus 321 down over the sinai desert, killing all 224 people on board. If proven, it represents a new and more lethal isis capability with farreaching security implications for Airline Passengers and beyond. The story is still developing developing. Lets get right to cairo andndur bill neely is there with late details. Reporter for five days investigators haveearched the wreckage for clues that caused a mystery. Now a u. S. Official tells nbc news, evidence indicates it was like by a bomb. The suspicion, it was placed on board by ground crew or baggage handlers and t tt isiss is respononble. It is a strong suspicion, not a conclusion. And no evidence of a bomb has been found yet in the debris. But it is a suspicion shared by britain. We have concluded that there is a significant possibility that that crash was caused by an explosive device on board the aircraft. Reporter brit app is suspending all flights to the a aport where the plane took off. Officials wont say if intelligence comes from the crash site or the flight data recorders which are still being an allized. And no one is ruling out the possibility of a technical fault on the plane. One hard piece of evidence, a u. S. Satellite strongly suggesting an explosion. A heat flash detected at the time of the disaster can only have come from a catastrophic fault, causing the fuel tank to explode or a bomb. Russian doctors report the injuries of those in the back of the plane match an explosion. But the mere suspicion this was a bomb raises the disaster to a new level. L. We obviously havav a strong desire to get to the bottom of what exactly happened there. Getting an explosive device on to an aircraft in this region is a gamechanger for security. U. S. Aircraft have long been warned away from the area. The faa advising airlines should avoid into or over the Sinai Peninsula. If there is a bomb there will be exelosive evidence and res due and evidence of a timer. No one has found it yet but there is growing concern. And today isis repeated its claim that it bombed the plane but it gave no evidence. Tonight the head of thth airport from where the plane took off has been fired and investigators have discovered lax security above all, and those who have access to the runway and to the planes. Lester. Bill neely in cairo. The brutality of isis has been well documented but successfully blowing an airliner from the sky wouldake the terror group into uncharted territory. We get that part of the story from richard engel. Reporter if isis did bring down the russian plane with a bomb, then the group which few had heard of only two years ago will have proved it has not just ambitions, but also deadly reach. In just a year, despite,000 u. S. A a coalition airstrikes, and the occasional soon to become more frequent special forces raid, isis has spread far beyond its strong holds in syria and iraq. In fact, u. S. Military officials tell nbc news they worry about the growing signs of isis presence in a half dozen other places. Afghanistan, west africa, libya and in the Sinai Peninsula where the Egyptian Military has been battling isis for months. Why is isis spreading so rapidly . With its mountains of cash and savvy online recruitment, isis is more open to newcomers than al qaeda ever was. Terrorists have always targeted planes, but in the posos 9 11 world, increased security hasade them more difficult to attack in the u. S. And many other places. That is one possible reason why isis would target the lowcost russian charter, flying out of a small egyptian airport. The other reason russia has declared war on isis in syria. A senior u. S. Official told me a short while ago, thatquote, the confidence is there that a bomb brought down the russian plane. And he expects russia to retaliate heavily and milt airily against isis in syria. Richard, thank you. Lets bring in the former director of the tional counter teorism center under president obama and bush. Now the executive Vice President of lydeos which does National Security work for the federal government. Michael, what are you hearing from your sources about all of this. Lester, people are look at two pieces of this. The circumstantial. And the vulnerability of the airport for poor scrcrning is there. And really the capability i think is largely there, even if this is an upgrade. And now it is the more direct evidence. Not just the flight path, but also signals intelligence and other indicators that, in fact, isis or isis affiliated groups were looking to target this. So i think on both of those fronts, circumstantial and direct, there is growing confidence that this could well have been a bomb. As weve noted, this plane originated from a nonu. S. Airport but what ought we to think about as we approach getting on airlines with this potential new threat from isis out there. The good news is really since the underwear bomber, the Christmas Day bomber in 2009, any plane which is flying to the United States orrrom the United States, there is much better screening that goes on. The challenge here is those same standards probably werent adopted. So small airports like this in this region absolutely more vulnerable. Michael lighter, thank you. Tonight there has been a shocking turn in the case of a Police Officer shot dead in illinois. A story we covered extensively. The manhunt for his killers. But knouff investigators say the officer killed himself. Part of an elaborate, carefully planned suicide plot after years of stealing. Crimes of authorities called today the ultimate betrayal. John yang now with the stunning developments. Reporter just two months after officers from across the country mourn lieutetent Charles Joseph glenno witz, the stunning announcement. This officer killed himself. Authorities said he was stealing from a Police Program for young people and laundering the money for some seven years. That he killed himself because he feared an audit was about to uncover his criminal ts.

Youll have to start dumping money into that account or you will be visiting me in jail. Today officials defended the massive days long manhunt for the three men glenno witz claimed he was pursuing. Costing nearly a quarter of a Million Dollars the first day alone. They allege it was a carefully staged suicide. He first dropping his pepper spray. A few feet later his baton and then his glasses. Killing himself. His semi automatic weapon founds 2 1 2 feet from his body in a grassy field. He had significant experience staging mock crime scenes. Even the two gunshots were carefully planned. Investigators say the first hit his cell phone and bulletproof vest. The second fatal shot was fired into the upper chest from a gun placed under the bulletproof vest, hihiing a major artety. He was my best friend. My world, my hero. When asked if his wife knew about the theft, police wont answer n. A statement her lawyer said the family is cooperated with the task forces investigation and will not comment at this time. In fox lake today, anger and disbelief. He was too good of aaerson just t tdo that. I dont believe it. Reporter while closing the books on glenno witz death, police have turned up strong indications of criminal activity on the part of at least two others. And that investigation, they say, is open and ongoing. Lester. John, thank you.
