Pennsylvania: Carbon monoxide Kills 4

Carbon monoxide apparently killed a married couple and their two children in an eastern Pennsylvania home where police found a car running in the garage, stunning friends and neighbors who recalled the family Tuesday as happy and outgoing. It wasn't clear whether the car was left running accidentally, or whether it was an intentional act. State police declined to comment on the investigation. Police were called to the home in Milford Township in rural Bucks County, about 45 miles northwest of Philadelphia, at 11:20 p.m. Monday. "When troopers arrived at the residence, they found the house was clearly filled with high levels of carbon monoxide from a running vehicle in a garage below (inside) the residence," state police Lt. Vincent D'Angelo said in a news release. Opinion: Maybe they shouldn't of parked in the garage if it was an accident, but if it wasn't then they should of made sure that the keys were with them and that the garage door was locked.
