'We will keep searching indefinitely' for missing Helen Robertson
Helen Robertson has been missing since July 5
The extreme heat and the length of time she's been missing are "all concerning factors for us," but Halton police say they're not giving up the search for Helen Robertson.
Robertson is a 79-year-old woman with Alzheimer's who was last seen at home in Burlington on July 5.
"We cannot stop trying and we will not stop trying" to find her, said Sgt. Barry Milciw with Halton police.
"We will keep searching indefinitely," he said. "Unfortunately I'm not aware of any new sightings."
Relying on tips now
The nature of the search has changed.
Police stopped their extensive ground search a couple of weeks ago after using a helicopter, canine units and volunteers to comb the area around Robertson's home.

They've been mainly relying on tips since.
'We searched everything. Every backyard. Every woodlot. Every pathway. We left no stone unturned," Staff Sgt. Ron Hansen told CBC Hamilton then.
Patrol officers are still keeping at eye out, collecting video and following leads. But police have done a targeted search of every possible hazard area around Robertson's home, and they've stopped.
'When you put yourself in the family's shoes'
Staff Sgt. Stephanie Jamieson asked anyone with information to call 905-825-4747 ext. 2305.
"We still have a tipline that's out there," she said. "We really need information from the public."
But she said the search continues.
"Obviously, we don't know what's happened," she said. "When you put yourself in the family's shoes, you would hope that no one would stop looking."
