Diners at the Roadside Breakfast Café on Interstate 84 fled to the parking lot in a panic yesterday afternoon when a man entered and began shooting patrons inside, killing two.

The couple – John and Lucy Madson – were having lunch when 26-year-old Andrew Hughes entered, wielding a Smith and Wesson 59 pistol, according to police. Witnesses claim the perpetrator was muttering to himself as he approached the smoking section and opened fire into the first occupied booth, fatally wounding the Madsons. Soon after, he turned the weapon on himself.

All three were taken by paramedics to St. Alphonsus Regional Medical Center, where John Madson and the shooter were pronounced dead. Lucy Madson, 37, remained in critical condition for several hours but did not survive the night. Police are investigating Hughes’ work and personal background, but as of this morning a motive for the attack is unknown.
