There is no doubt that this crime was carefully planned. The location and timing of the killing indicated that as well. Boris Nemtsov was going with his female friend to ‘his apartment, which is located close to the murder scene’... The organizers and the executers apparently knew his route
But it’s more fun to say this was close to the Kremlin rather than that he lived nearby.
Yep, walking in the middle of the night, on a bridge, yet less than a month prior Nemtsov wrote, "I'm afraid Putin will kill me", which also appeared on various news sites.
