Everyone who knew Patrick Duffy or his parents were understandably shocked by their violent deaths at the hands of Kenneth Miller and Sean Wentz, who were quickly tracked down. As the Associated Press reported in 1987, the teenagers were convicted and given 75-year sentences for each murder, in addition to 30 years each for robbery and assault charges (per UPI, Wentz later received an additional 10 years, explaining that "the Miller jury sent a message that Sean Wentz was the triggerman.") 

Duffy's sister, Joanne, who became a police officer, was reportedly disappointed that they hadn't been given a death sentence. The famous actor was able to find peace, however. "My sister immediately was on a campaign, wanting punishment," Patrick Duffy admitted to The Times in 2012, sharing how some of the Duffy family disagreed with his pragmatic approach. "My attitude is they're already punished. They created the cause for the misery of their lives to come." Even the news that Miller would be released on parole in 2007, after Wentz admitted that he was the sole gunman, didn't shake the "Step by Step" alum.

"I'm okay with that. My sister's not," Duffy revealed, observing that the pair weren't master criminals. "They're stupid young men, really stupid young men."
