I came up with a theory to explain why Richard Allen may not have heard Liberty German's phone. After crossing the creek, at 2:32pm the phone stops moving. Richard Allen then commits the murders over the next 20 minutes but does not stay to make sure the girls are dead while possibly listening to the phone ringing.
He leaves at around 2:50 - 2:55 pm from the crime scene and walks back to his car. Maybe he is even able to still use the trail path before Liberty German's father shows up to be able to walk back to his car. This would then mean he drove away from the old CPS building at around 3:30pm like he originally told the conservation officer. This also gives him time to go to CVS to dispose of the box cutter in the dumpster and then drive home to get cleaned up and drink the other 3 beers.
The only problem is who did SC see at 3:57pm walking along 300 N?
2 of the 4 girls at Freedom Bridge testified to seeing BG, Betsy Blair testified she saw BG on the MHB, SC testified she saw BG along 300N. RA was not in his car prior to SC seeing him, as no one else driving along 300N reported seeing him/BG & he was never seen by the HH store camera, nor by 3 witnesses on the trails in the MHB area during & after the murders.
He had roughly, at a minimum, 1hr & 20min to murder the girls, move 1 or both bodies, cover them with leaves, sticks & branches & make his way 1/4 of a mile north to 300N. He certainly didn’t kill them & leave. He didn’t need to rush, as no one on the bridge (arguing couple - CM, flannel shirt guy - DM) testified to seeing anyone described like BG or hearing screams or yelling when asked by the D, which would include DG yelling. If they didn’t hear DG, I don’t see RA hearing DG either.
He either ignored or did not see/hear the phone. I tend to believe it remained hidden & he never saw or heard it, just like he never saw the round ejected from his gun when, for whatever reason, he racked it.
Only RA knows what occurred after LG recorded him & prior to being seen by SC. Only RA knows where he went after being seen by SC. Unless RA decides to give the details, it’s anyone’s guess, really. I’m sure you’re not the only person who has questions regarding every detail of the crime & why certain things remain undisclosed. Maybe once the gag order is lifted, more details will become available to the public.
ETA or anyone described like BG
