Police interrogations are not always difficult or boring.

We have you on the beach at the time of the murder and they're running DNA samples. Are you sure there’s nothing you wanna tell us?
I don’t even know why I’m still here.
-Guys, we don’t have enough to hold her. -Aww...

ON THE BEACH= Remember the preposition ON with "beach"

DNA= Deoxyribonucleic acid. The cell part that carries the genetic information.

SAMPLE= A specimen, an example, a portion that is representative of a whole.

WANNA= Want to

GUYS= Boys, men (coll. AmE)

HOLD HER= Keep her from departing. If the police holds someone they don't let them go. If you hold your mother, you put your arms around her, you embrace her.
