Anyone else having trouble finding suspects in the detective career path?

After interrogating I get a message to release the innocent suspect. Everyone at the park was pointing to her...and it does say jeans, jacket, grey hair and elder. Hmm. There was one person who match the description but was bald.

EDIT: It was the bald guy...and I had asked him where the suspect was and he pointed me to the woman above. Gah. Is there any theories to how to get the suspects to confess quickly in interrogation? Do we just hit them with evidence or a bit of good and bad cop too?
