An employee at a Wisconsin software company opens fire at the office, wounding three coworkers and forcing others to hide under desks. A gunman wounds four people at a Pennsylvania municipal building about an hour and half later, before he's shot dead by police. The next morning a disgruntled employee fatally shoots three people and leaves three others wounded at a Rite Aid distribution center in Maryland.
