Andy Parma is Columbo's nephew. His father was Columbo's brother, and tragically both of Andy's parents died in an airplane crash when Andy was young. After this he began to look up to his uncle like a father, and followed in his footsteps by joining the Los Angeles Police Department, eventually making Detective. He became good friends with fellow officers Robert Goodman and Dennis Mulrooney.
In 1992, Andy married the love of his life, aspiring supermodel Melissa Alexandra Hayes, but disaster struck when Melissa was abducted from their hotel bridal suite by deranged stalker Rudy Strassa. Andy, his friends and veteran uncle were soon on the case, and thankfully managed to rescue Melissa before she could be killed.
Andy appeared in No Time to Die, played by soap opera star Thomas Calabro. Andy is the only member of Columbo's family to ever appear on screen in the series.
