I was called early one night when the family and neighbors were hearing the things vocalizing along the creek. I begin driving over and made the last turn less than 100 yards from their house. In making the turn I saw a flash of red eyes down along the creek, and i nearly ran over a man that was hauling tail in the street with his back to me. I knew him, tooted the horn and he stopped. He was very agitated and I asked what was going. He said," One of those SOB's d--- nearly hit me with a rock.". I parked and asked where he had been standing. We walked back to the spot. He had been on the side of the street nearest the creek shining a huge, high powered light, and heard the rock breaking limbs, and then saw it in midair in light's beam as he ducked it. I looked across the street and saw where the rock hit the asphalt and skidded to a stop against the curb. I picked it up and saw that the fist-sized rock had wet creek mud on the exposed surface. While looking at the rock (igneous quarry stone), he took it out of my hand and kept it. The next day I was able to see where a BF had steeped off the bank on the opposite side of the creek into the rocky creek bed then jumped about six feet onto the side the man was on. (The bank was only about two feet high at that point.) That's where the BF had been when I saw it's eyes, and apparently where he stood to throw the rock.
One night some time later, the lady called to say her house dogs were barking like crazy and looking toward the swimming pool. She could see nothing moving but saw big tracks of water on the tile surrounding the pool. I drove over and found that a BF had climbed over their high wood fence around the pool area at a corner where a medium sized tree grew on a neighbor's property. The incoming tracks in the grass, and the abraded bark on the tree were obvious. There were no incoming tracks noticed on the tile around the pool. What were very obvious were the tracks of a BF that had walked out of the pool on the steps, then made a left turn, walked to the corner of the pool on the tile and made another left turn then angled off the tile into the grass and climbed back over the fence at the tree's location. The length, width and stride of the barefoot tracks ruled out humans. (Had a human tried to make "jumping" tracks with wet feet on that tile he would have busted his.... backside.
I was investigating the report for the BFRO. I was obligated to keep the names, locations and other personal info confidential. Since the young man had already been posting information on a blog about what was going on, I saw no point in going any further with a report for publication. (His mother did not know what he had done and had - what we call in the South - a "hissy fit" when I carried her a copy of what he had posted on his blog.)
Her three sons, all in college, are as bright as the evening star, and very courteous and likable. Good young men.
Hope this answers your questions OldDog.
