Shooting

On 10 August 2018, around 7:00 a.m. ADT, multiple witnesses reported dozens of shots being fired on Brookside Drive between Main Street and Ring Road in a residential neighbourhood on the north side of the city of Fredericton. At 7:10 a.m., Fredericton Police officers Lawrence Robert Costello and Sara Burns responded to calls of shots being fired outside of an apartment building. They arrived to the scene of two people on the ground and were fatally shot upon approaching them. The area was locked down by Fredericton Police, who told residents to stay in their homes.

Editorial analysis

Why this record matters

“2018 Fredericton shooting” is worth following because a concise public description often conceals a longer documentary argument. Here, Fredericton, shooting and Canada provides the most credible route into that argument.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q56043189. Authority coordinates are 45.988, -66.654. None of the 1 selected statements returned an explicit reference.

Critical limits

The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
