After the First 48 S04E10 - The Ring / House of Pain

In Birmingham Alabama a mother of a two-year-old boy is found stabbed to death in her own bedroom. Investigators have a mystery on their hands when they learn the killer opened the victim's front door with a key and stole her diamond ring. In Cleveland Ohio, two 19 year-old men are shot and killed during a party at an abandoned house. All signs point to a good friend of the victims' as the shooter but no one actually saw him pull the trigger. With no DNA or murder weapon found, the state needs to convince a jury the defendant is a cold-blooded killer.
