"Search parties scoured the base of the bridge and surrounding trails Monday night, but darkness made the searches nearly impossible" Leazenby said. "With darkness last night, we probably didn't pick up on everything," he said. "With daylight in our favor, we're sending folks back out to basically back track where we've already been".....
It would have been quite risky to move two bodies likely having to make two trips especially once the search began in the area the same evening. It was dark, and their bodies may have been difficult to see. IMO, they were probably there from the time they were killed.
Years ago I was on a search for a missing elderly gentleman whose car was found in a parking lot near a rural park. I was called in on the 4th morning of the search. For three days prior, mostly during the daylight hours, the entire San Antonio Mounted Police (12 of them), The Heidi Search Center, the missing persons detective in charge of the case, numerous LEO's, and numerous other volunteers searched the entire area.
On the 4th morning I was teamed with a group that was to head North then East. We headed North, and just as we were about to head East, my dog hit to the West. My dog air scented, and the wind was blowing from West to East. I radioed to base camp to ask if the area to the West had been searched, and I was told it was searched twice. I asked to bring the team I was with to the West instead and was given the okay. My dog first found a pair of brown alligator men's shoes and then took off and found the gentleman's deceased body about 30 feet from the shoes and about 8 feet from a small creek. This was the shortest search I had ever been involved in. From the time we left base camp until my dog found the gentleman's remains only 5-10 minutes had passed. It was not that my dog or I were better than the other dedicated searchers that day. My dog had a good nose and the gentleman's remains were close to where he hit. The whole area was pretty heavy with brush and trees which makes for good camouflage.
I always leave room for doubt or that perhaps that the girls were moved later. But, just because they were not found the first night, in the dark, does not mean the girls were moved after the area in which they were found was searched from my experience, and in my opinion. I am not verified, but I hope it is okay that I posted this. I just wanted to help by sharing my experience.
