I don’t know which is correct but I always tend to rely most on information published by local media. By the time the killer was travelling toward Halifax on hwy 102, he must’ve already been under the scope as they knew what vehicle he was driving. For that reason I don’t think he had any further opportunity to commit any other murders even with the intention of stealing a vehicle with a full gas tank and it appears he had no choice but to stop for a fill-up not even realizing the RCMP were on his tail. But as for news reports, of course this could also be subject to change.
