About 5:45 P.M. 4/24/64 while in Socorro 2 Police Car (64 Pontiac white) started to chase a car due south from west side of Court House. Car was apparently speeding, and was about 3 blocks in front. At point on Old Rodeo Street (extension of Park St. south) near George Morillo residence (about 1/8 mile south of Spring Street, the _____ chased car was going straight ahead toward rodeo grounds. Car chased was a new black Chevrolet (it might have been _____ boy about seventeen). Chased car still about three blocks ahead. _____ alone.` At this time heard a roar and saw a flame in the sky to southwest some distance away--possibly a 1/2 mile or a mile. Came to mind that a dynamite shack in that area had blown up, decided to leave chased car go. Flame was bluish and sort of orange too. Could not tell size of flame. Sort of motionless flame, slowly descending. Was still driving car and could not pay too much attention to the flame. It was a narrow type of flame. It was like a "stream down"--a funnel type--narrower at top than at bottom. Flame possibly 3 degrees or so in width--not wide.
