This context comes from the 2007 movie "Zodiac" by David Fincher.
Captain Cross:"..I also told him we don't think this was Zodiac. We have a guy we like for it. Don't have enough to make it stick yet, but we're pretty sure it's him."
A similar sentence appeared later in the movie
Tosci: "For now. If we get something, Mulanax will take it to the Vallejo DA to search the house properly. We also talked to the cop who interviewed Allen before. Doesn't remember how he got onto him but said he didn't look like a killer, so he didn't like him for Z."
Is this just the common meaning of "like" meaning (to wish to have: as in would like a drink(Merriam-Webster)) or is there something else at play here?
