Answer
Emery committed the crime.

Reasoning
If we assume that Alex was the culprit, we can see that there would be 6 true statements, but we know there were exactly 5 true statements, so it can't be Alex.

We can repeat this will all five suspects and quickly see that only Emery being the culprit would result in exactly 5 statements being true.
