Twin Killers Grab Spotlight Again
Investigation Discovery explores nature versus nurture on series
Identical twins Robert and Stephen Spahalski tried to one-up each other by committing murders. Now one's serving a life sentence and the other is on the lam.
The brothers' sick and twisted way of life has been covered on a number of networks, including truTV and are now the subject of Thursday night's episode of "Evil Twins" on Investigation Discovery.
Unlike on the other specials, the producers of "Evil Twins" will explore whether the Spahalskis became murderers because of something sinister inside of them or because of the violent, drug-induced culture they worshiped.
"Evil Twins" airs Thursdays at 10 p.m. ET/PT on Investigation Discovery.
