No body? No problem in most murder cases

NEWARK, New Jersey - Police in the US state of New Jersey believe they have solved one of the longest-running murder cases in the state's history: the disappearance of five Newark teenagers in 1978.

After tracking leads for 32 years, two men were arrested on March 22 and charged with herding the teens at gunpoint into an abandoned row house, tying them up and torching the building, setting a blaze so fierce police say the bodies were incinerated, destroying any evidence.

Now, prosecutors have a difficult task: Prove the teens were murdered when their bodies were never found.
