Fargo, ND (AP) — Hundreds of people packed into a church in Fargo to honor and remember a West Fargo police officer who died of a massive heart attack while at work.

Police Lt. Adam Gustafson, a 10-year-veteran of department, died last week at age 40. KFGO radio reports that the turnout at his memorial service Wednesday included strong support from law enforcement, firefighters and other first responders. West Fargo Police Chief Denis Otterness remembered Gustafson as someone who brought a positive attitude to the job. Gustafson was known as a jokester, tossing a football around the police station and doing cartwheels in the hallway.
