How could there not have been time for it to go out if he heard it ?
Do you know how far the QT and Liquor Store are from the street in front of the apartment complex where Brown was living with GRANDMA was ?
Hopefully this will help you get a better grasp of the timeline.
Address of Shooting - 2900 Canfield Drive, Ferguson, MO.
Address of Ferguson Market and Liquor - 90 W. Florissant Ave. (.6 miles, walking time 11 mins. from apartment complex)
Address of QT -9420 W. Florissant Ave. (reported 1/4 mile from the apartment complex)
I am going to answer this (Google the addresses).... The Quik Trip (10768 W Florissant Ave St Louis, MO 63136 - located north of Canfield) was not where Brown was. Brown lifted the cigars from Ferguson Market & Liquor. (9101 W Florissant Ave, St Louis, MO 63136 - near Ferguson Ave south of Canfield) - the report was Perps were headed in the direction of the Quik Trip (heading north up W. Florissant when they left the Ferguson Market - now look at a google map and locate these addresses)
Brown was shot on Canfield Court. (more than likely they did not walk up all the way up W. Florissant Rd to Canfield.) They probably walked behind the shops on the east side of W. Florissant and probably went up Ellison Dr to Canfield.
Why did Quik Trip get burned down. Probably because Dorian LIED to local people in the neighborhood and said they were walking back from the Quik Trip (not mentioning the Ferguson Market so that he could keep his story going - then boom and few days later the tape is released that they were at the Ferguson Market and Ferguson Market is hit that night.)
I will add that every night you see the protesters marching up and down W. Florissant. They are marching from Canfield Dr (Canfield is just south the Quik Trip) to Ferguson Ave. (which is near the Ferguson Market). Walking up the east side and down the west side of W. Florissant. As you can see that the walk does not take that long to complete. It is a long block. Chances are that Mike & Dorian may have even jogged back to Canfield Dr up Ellison Dr.
Some one posted a media diagram map earlier that was from a article. (that diagram was upside down - it showed Canfield on the southwest end when actually it is on the northeast end) - I mentioning this as it can be confusing to people who are actually looking a online map of the area.
