(AP) — Attorneys in the case of Colorado movie theater shooter James Holmes began giving opening statements Monday, marking the start of a long-awaited trial that is expected to take months and include emotionally wrenching testimony. [...] prosecutors allege Holmes planned the violence for months, amassing an arsenal that included a rifle, a shotgun, two pistols, tear gas canisters and body armor. The trial comes after 2½ years of complicated legal questions related to the death penalty and the insanity plea, and after nearly three months of jury selection. Victims in the shooting at the Century 16 movie theater include a 6-year-old girl, two active-duty servicemen, a single mom, a man celebrating his 27th birthday and an aspiring broadcaster who survived a Toronto mall shooting.
