"Dallas researcher Michael Brownlow interviewed Doris Holan, who lived directly across the street from the shooting, in a second-floor apartment at 409 East Tenth (researcher Bill Pulte accompanied Brownlow on one of his two interviews with Holan shortly before her death in 2000). She said that a police car had appeared in the driveway between the two houses (404 and 410 East Tenth) at the spot where Tippit was killed. Whether Tippit did so intentionally or coincidentally, he had blocked that driveway, which led to an alley at mid-block, parallel to both East Tenth and Jefferson Boulevard. Tippit, while driving eastward, may have been trying to use his squad car to prevent another police car from leaving the driveway. Holan said when she heard shots and looked out her window, the other police car was heading down the driveway approaching Tippit's vehicle.
... 'She saw a man leaving the scene, moving westward toward Patton... Near the (second) police car she also saw a man in the driveway walking toward the street, where Tippit's car was parked.' That man went up to where Tippit was lying, looked down to inspect the officer's head, and retreated back down the driveway, with the unidentified police car backing up at the same time to the alley. So Holan reported at least three suspicious men at the scene, including two men on foot and the driver of the second police car. Whoever killed Tippit may have fled in that car or in another vehicle or on foot through that alley adjacent to the shooting scene. And Tippit may have been shot by two men, a possibility the ballistics evidence, with different kinds of ammunition, might suggest, even though that evidence is unreliable. Most (not all) witnesses reported a man fleeing around the corner and up Patton toward Jefferson, which would be compatible with Holan's account.
