IMO, the traveling trio was nowhere close to arriving in Salida anytime close to dinner time -- let alone lunch!
We know that CCSO did not meet Ritters in Maysville to take the missing person report until sometime after 6 pm. It was much later (after the bike recovered) when LE arrived at PP and first spoke to MH before his dad and sister arrived. At this time, dad and son were very clear to say the daughters were on the road but made no indication or assurances that they were near and/or approaching Salida.
I think it was around 9 pm when BM arrived at the bike scene where we also saw Mrs. H who I doubt would have been at the scene looking for her husband and son if the daughters were already in town. It seemed to me from the deputy's response that father and son were waiting somewhere nearby -- perhaps the Ritters because we know that the house was on lockdown. I really would not be surprised if traveling daughters did not arrive until after midnight or early AM.
From the CCSO press release, we know that dogs began searching after BM provided them with SM's clothing (as seen in the recently released video), and searched well into the early morning for SM.
Sheriff personnel called members of Chaffee County Search and Rescue South and North and a search began immediately. The Department of Corrections was contacted and a request was made for tracking dogs to assist. They responded and joined the search. The search continued into the early morning hours with no results.
The search resumed in the early morning hours of May 11 with Search and Rescue. They once again scoured the area. Members were then called from the Chaffee County Tac Team along with search parties from the Department of Corrections and the area was once again scoured.
