So looking at his "house" on google street view, the back alley actually has 6 electric meter boxes. I believe its a 6 unit place which any unusual noises should have been noticed? I live in the area and the walk to Syntax is very easy. I keep hearing when he left syntax, he crossed the street in the opposite direction of his house. To me this means he crossed Broadway which is pretty busy even at 1am and there is no corsswalk by syntax. I don't see why he would park across Broadway when there would be plenty of parking on the syntax side of the street. Also there is way easier neighborhood parking AND syntax has its own parking lot in the back. Crossing Broadway is the strangest thing to me because there is nothing open on that side at 1am. There are some apartment complexes (Denizen) that way where he could have been meeting someone. There is also the river but its incredibly hard to get to because you have to cross the highway unless he walked up to Alemeda. Earlier in the night He was at Triangle (maybe alone?), then Charlie's (alone?) , then Syntax (alone?) so my best guess is he wanted to be social and meet people.
