The Texan connection was made by media outlets, AFAIK.
The theory that the RCMP are exploring does make some sense, as you've got a torched vehicle with missing occupants just down the road from a deceased male found in a roadside stop, but without a vehicle. How that connects to the other two homicides is less clear.
To add to all this:
The pair is no longer considered missing.
It's believed they have left British Columbia and they have been spotted in Saskatchewan. RCMP said they were last seen driving a grey 2011 Toyota RAV4.
RCMP said they may have changed their appearances and have asked anyone who sees them not to approach them.
B.C. RCMP named the pair as suspects during a press conference from its headquarters in the Lower Mainland at 11 a.m. PT on Tuesday.
