Who killed Caspere? Oh, I don’t know. We just have about 40 suspects. (Spoilers ahead).

In Episode 6, Frank talked to Ilena, a Mexican prostitute who said a cop paid her to pawn Caspere's goods (which conveniently framed Ledo Amarilla and made him the number one suspect in Caspere's murder).

Unfortunately, before Frank could have Ilena identify which "tall, white, skinny" cop gave her the items to pawn, she is killed by "Gonzales," the two men who weirdly have one collective name. The two used this as an opportunity to blackmail their way into moving product through Frank's clubs.
