LE has stated that they think he was at Lake Cachuma all day. He was seen at the Lake Cachuma Rec Area store (some time within 11:30 - 2:30 ???) purchasing items, and his car was jump started in the Lake Cachuma area, although we don't know what time. LE has stated that they think he was at Lake Cachuma all day.
One can only conclude that he was in the areas of Nojoqui Falls and Solvang some time between 2:00 am and 8:00 am. If you consider driving time either way, it sounds like you can shave off at least 1 hour from each end to account for travel time. Therefore, if my math is correct, they would actually need to figure out what he was doing between Nojoqui Falls and Solvang between 3:00 am and 7:00 am.
