About Holan and Tatum....
Did Brownlow ever check Holan's bona fides? By that, I mean was he able to determine that she actually lived at that address at the time? Any latter-day witness "find" needs to be treated with a bit of caution, and no one else ever reported either the extra squad car in the driveway, nor the guy walking out to Tippit.
Which brings me to Tatum. He was supposedly driving by Tippit's at the time of the shooting, but no one else remembered a car doing so at the time.
Yes the driveway between 404 and 410 I cannot really respond whether it was proven she lived at the apartment Here is a better quote on Guinyard
Mrs. Holan?s account of a second police car is supported by the comments of Sam Guinyard, who told Brownlow in 1970 that he saw a police car in the alley shortly after the police shooting. The man in the driveway was apparently also seen by others: a resident of the neighborhood, who wishes to remain anonymous, told Prof Pulte, in 1990, that he had heard about a man in the driveway who approached Tippit?s car.
Frank Wright, who lived half a block east of the shooting, told reporter Earl Golz that he saw two men involved in the crime. But that was a belated addition to his earlier account of seeing one man drive off in a car. To Golz he mentioned another man fleeing on foot.
...independent researchers George and Patricia Nash ...in 1964... reported Wright telling them that after hearing the shots, he came out of his home at 501 East Tenth and saw Tippit hit the ground and roll over after being shot. Wright said he saw a man standing near Tippit, not holding a gun but wearing a long coat (contrary to most other witnesses' description of a fleeing man wearing a light jacket), run away and drive off, alone, in a 'grey, little old coupe. It was about a 1950-51, maybe a Plymouth'.
