It's a long night in the Crime Lab, LVPD never sleeps, and neither does Hodges. This case is a difficult one, three dead women, no evidence apart from hair strands, and several suspects all of whom have alibis.

Having found some composites on the windowsill of the room the women were found in, Hodges analyses the composites. He slides the glass slits into the microscope, carefully looking for anything that come up with answers.
