CSI: Miami Season 8 Episode 22

Laura Williams is beaten to death with furious force, just after her and husband Chuck's 20 wedding anniversary. A video camera found on site recorded her walking in on Chuck's apparently intimate conversation with their son, Cody's, history teacher, who is convinced control freak Laura physically abused the kids, which Cody and sister Andrea ultimately confirm. Eric is most uncomfortable when the prosecutor's office charges him with checking up the CSI staff's personal finances after the diamond theft from the evidence room. $25,000 is found on Walter's account.
