Calgary police are looking for a pickup truck and its driver in their investigation into the Amber Alert case of a missing five-year-old boy and his grandparents. Police said Friday a truck was spotted in the area on Sunday night when the three were last seen.
It's described as a late 80s or early 90s green Ford F-150 in
very good condition.
Nathan O'Brien and Alvin and Kathy Liknes were reported missing
Monday and police believe their disappearance is suspicious.
The boy had been at his grandparents' on a sleepover after the couple held an estate sale at their home on the weekend.
Staff-Sgt. Doug Andrus says police found forensic evidence at the home, but didn't say what it was.
He says police believe it was from someone in medical distress.
The evidence has been sent to a police lab for analysis.
The Amber Alert remains in effect.
Police had been looking at closed-circuit video and have received hundreds of tips from the public.
``We have no suspects we can name, but ... we have information that's allowed us to move forward with this investigation,'' Staff Sgt. Doug Andrus said at a news conference Thursday.
Police aren't calling the driver of the truck a suspect but believe he may have more information about the three missing people.
Investigators spoke with about 75 people Thursday who attended
the estate sale at the home.
It's believed more than 200 people were at the sale and police continue to ask anyone who may have attended to contact them.
