any other dna on it besides his own. what about the hand writing of that letter? is it in his handwriting or somebody els? they re going to look close and find out if he was affiliated with anybody else or anybody else knew about this attack. when he rented the truck, did he use his credit card, or was somebody else with him at the time when he rented the truk? they re going to check his apartment, was there any other dna in the apartment? track that person down, did that person know about the attack? a lot of work to be done here, but there s a lot they can find out while they re conducting their investigation. is it always people can use whatever excuse they want for their own craziness or their own issues, right? and it could be he s so angry and he s so upset, and he s just using this isis thing as an excuse, who knows. it s very possible.
ways wins. especially in my business. with slow internet from the phone company, you can t keep up. you re stuck, watching spinning wheels and progress bars until someone else scoops your story. switch to comcast business. with high-speed internet up to 10 gigabits per second. you wouldn t pick a slow race car. then why settle for slow internet? comcast business. built for speed. built for business. this is cnn breaking news. the suspect in the berlin market attack, the christmas
