a busy weather weekend. a d.c. murder mystery, and hacking into the cockpit? let s zoom through some of today s top stories. it was a wild weather weekend after a powerful storm spawned 34 tornados. this was the damage left behind in southeast louisiana. check out this video of a twister in elmer, oklahoma. the cows unphased by the weather around them. the system is now headed through the central plains and going towards canada. more trouble expected in texas over the week already being hit by major flooding. these are dramatic rescue pictures from the weekend. the lone star state expected to see daily downpours and the chance for more severe weather. now to a murder mystery in the nation s capital and surveillance video police hope will help track down a person of interest in a fire that destroyed a multimillion dollar home and prominent d.c. neighborhood. four bodies were found inside the house believed to be a couple, their ten-year-old son and their housekeeper. police believ
what happens next caught on surveillance camera from a nearby building. watch as sparks fly as over 100 miles an hour. the deadly speed catapulting seven train cars and the engine off the tracks. we will have positive train control on the northeast corridor section by december 31st. reporter: amtrak s ceo says that safety mechanism to prevent human error will be in place by the congressional mandate. but some say too little too late. why isn t it done now? was it an issue of cost? has it just come down to the bottom line? no it s a time issue and also a cost issue. reporter: all right. back out here live this morning cnn has also learned an automatic braking system has been in place for years on the opposite side of the tracks to slow trains going southbound trains from new york to d.c. as it enters that curve. however, that slowing mechanism is not on the side of the tracks where this accident happened.
with that engineer will be critical. right, and it will be a formal interview with all the parties to the investigation, including amtrak and anybody else that may be a party to that investigation. how hard is it going to be to establish a manifest of the passengers given the fact that although the train tickets i gather are computerized even on unreserved trains people could decide at the last minute not to get on. yes. that s been a problem. any passenger trains that s been the ease of tracking passengers on aircraft but not on passenger trains even on subways, always a problem finding out how many were on the train at the time of the accident. these are the old metro liner cars that preceded the acela cars on the train. did this have an automatic braking system where you have to affirmatively put your foot on accelerator to keep going, sand there any sort of, you know automatic speed control similar
on the route going from washington to new york when a train also derailed. and we don t know for sure what the cause of this latest crash in philadelphia was, amtrak was in the process of installing what s called an automatic braking system though along the stretch of track where the crash happened. and jon, that was supposed to be fully in place by the end of this year. too late it seems like. leah gabriele gabriel, thank you. the system of roots on which the train derailed is the northeast corridor. it provided a critical link between the nation s biggest cities. the latest numbers from amtrak show back in march alone, more than one million passengers traveled along the northeast corridor corridor. that was nearly 40% of all riders across the country. laura inge sl live at the port authority bus terminal here in new york city now, laura. reporter: hi jon. this is where a lot of those displaced amtrak riders turned up today. many of them looking for the least expensive way to ge
yes, right. i m certainly not an expert on this but i read a paper years ago that i thought was interesting that talked about homeostatic risks. it was a theory about risk ee quul lib yum. you have a tolerance for risk and i have a tolerance for risk. statistically speaking, they re not the same. but as we begin to employ certain safety protocols, we will counterintuitively begin to assume greater levels of risk. therefore, you ride a motorcycle, you put on a helmet, you re going to drive a little faster. you drive a cab and somebody puts in an automatic braking system. they did this study in munich years ago. it was fascinating. they monitored the whole fleet of cabs and the drivers took more chances, cornered more sharply, got in more accidents. so the most dangerous intersections in the world are the ones that have signs that tell you when to walk because they train you not to look for the car. you are trained to look for the
