Oh dear, exactly. Not the best researched article (but this is the Express).
"Rainne" was / is, according to her twitter profile, a female life coach based in Hawaii. Her posts to @sweepyface on the 3rd October seem to be her first posts with anything to do with the McCann case or Sweepyface.
They were absolutely disgusting - but she is an equal opportunities abusive troll. She over the past couple of years directed very similiar foul mouthed tweets to US politicians, various celebrities, blacks, muslims, and has a particular dislike of mormons for some reason.
If the authorities actually want to track her down, her twitter account had some helpful selfies of her in various locations, and quite a lot of detail.
There is no reason to suggest she is a supporter of the McCanns.
