Stephen Paddock, the retired accountant who killed at least 58 people at the Mandalay Bay Resort and Casino in Las Vegas on Sunday night, was “slovenly” and “didn’t always make sense,” according to a lawyer whose firm ran across the shooter years earlier in an injury case he brought against another casino.

Martin “Marty” Kravitz, managing partner at Las Vegas-based Kravitz, Schnitzer & Johnson, represented Cosmopolitan Hotels & Resorts Inc. in a case Paddock brought alleging he slipped and was injured inside the casino. Kravitz told ALM that he spoke with the associate who handled the case, now at another firm, after getting calls from the media at 2 a.m. about the case.
