Oct. 18, 1972: Born in Newcastle, N.B. Wynn's family says his childhood revolved around the outdoors: fishing, camping, snowmobiling and riding dirt bikes. His family had a cottage at Oak Point, N.B., and he was active in the Boy Scouts.
1990: Graduated from Miramichi Valley High School and went on to study civil engineering for two years at Acadia University. He worked the night shift baking bread for Sobey and created a product known in the local community as "Davey's buns." He also became a scuba instructor.
1993: On the way to dive for scallops on Nova Scotia's south shore after a shift at the bakery, Wynn suffered serious injuries in a single-vehicle car crash. His family says the crash inspired him to take up a career as a paramedic.
1994: After recovering from his injuries, Wynn completed his training to become a paramedic in Bridgewater, N.S.
1997: Wynn met his wife, Shelly, in Bridgewater, where they were both Red Cross first-aid instructors. They married on Sept. 5 of the following year and had three boys — Matt, Nathan and Alex — in the following 2 1/2 years.
2009: Having been inspired by the Mounties he met on the job as a paramedic, Wynn entered the RCMP's training program and graduated from Depot in Regina. He was posted to the St. Albert detachment just outside of Edmonton. Wynn's uncle, retired sergeant Duncan MacInnis, presented him with his badge on graduation day.
Jan. 17, 2015: Wynn was gunned down while he struggled with a suspected car thief inside the Apex Casino in St. Albert. Auxiliary Const. Derek Bond was also shot, but survived. The shooter took his own life hours later.
