"He was found innocent."
How exactly does this work? Is it just an idiomatic contraction of 'found to be innocent'?
What about "He was found alive"? 'Found' here is working a lot like a causative verb such as 'made'.
{If I put a comma in here it is a different sentence. "He was found, alive." Then it's a parenthetical or perhaps some kind of parallelism ('he was found, he was alive'). Nothing mysterious about that.}
Is there a structure here that I'm missing? Something a bit like a causative verb, but not? There are simple and obvious examples: "It was built tall", "It was built to last", "He was worried sick".
