( CNN ) -- All Royal Canadian Mounted Police `` understand the risks that come with the uniform , '' Canada 's governor general said . Five Mounties surely had those risks on their minds this week when they responded to a call about a gunman in Moncton , New Brunswick . And it did n't stop them from defending the quiet , tight-knit community of 70,000 , located about 250 miles northeast of Bangor , Maine , Wednesday , their supervisors say . The call said the man , now identified as Justin Bourque , 24 , was on a Moncton road , wielding a firearm . Soon , shots rang out on the road , as Bourque fled into the woods , where more shots were fired . Over a `` short period of time , '' Bourque allegedly shot five officers , killing three and wounding two others , said Codiac RCMP Superintendent Marlene Snowman said . The two injured officers required surgery on Thursday , police said . One has been released , while the other remains hospitalized . Canada 's National Post newspaper is calling it the nation 's worst police tragedy in more than nine years , when four Mounties were ambushed and killed during a property seizure in Mayerthorpe , Alberta . Canadian media at the time touted that tragedy as the worst in a century . `` I ca n't begin to explain the sadness we feel . ... My thoughts and prayers remain with the families and loved ones of these fallen officers who died in the line of duty and our recovering officers , '' RCMP Assistant Commissioner Roger Brown said in a statement on Friday . He identified the slain officers : . -- Constable David Joseph Ross , 32 , of Victoriaville , Quebec , joined the RCMP in Ottawa . After graduating from the training academy in July 2007 , he began working in general duty policing in New Brunswick 's Codiac Detachment . -- Constable Douglas James Larche , 40 , of Saint John 's , New Brunswick , joined the RCMP in Moncton . He finished training in February 2002 and served in two posts before joining the Codiac Detachment where he worked in highway patrol and general duty policing . -- Constable Fabrice Georges Gevaudan , 45 , of Boulogne-Billancourt , France , joined the RCMP in Regina , Saskatchewan . He graduated from training in February 2008 and worked in general duty policing in the Codiac Detachment . The injured officers are Constables Eric Stephane J. Dubois and Marie Darlene Goguen , who are `` recovering well and are to be commended , '' Brown said . The assistant commissioner said he would provide more details on the slain officers and their funeral arrangements in coming days . The only other information he provided about the constables was that one of them had three children and that Larche received a commander 's commendation in 2008 for saving the life of an unconscious baby in Moncton . Ross was a police dog trainer and was married to Rachael Ross , who was pregnant with their second child , CNN affiliate CBC News reported . The couple already had a 19-month-old son . `` This is the most horrifying , difficult experience , '' Rachael Ross ' mother told CBC . The couple celebrated an anniversary last month , and several of Rachael 's friends on Facebook posted birthday wishes on her wall in May . Rachael Ross ' sister-in-law told the National Post that Rachael got home from work Wednesday , the garage door was open and the barbecue had been left on . Her husband had been called in to work and left hastily , she told the newspaper . `` All these guys were family men , protectors of our society , great guys â€ ” and Dave was one of a kind , '' Raquel Vander Ploeg said . `` Dave loved his job . He was good at his job . He was a police dog handler , and it was what he had striven to be for years , and he got it , and now this happens .
