The family of the retired New York Times reporter who was bludgeoned to death outside his Northwest Washington home filed a $20 million lawsuit Monday against the District and a D.C. hospital.

Former newsman David Rosenbaum, 63, was taking a stroll outside his Gramercy Street home in January when he was jumped from behind and struck repeatedly with a heavy plastic pipe. Last month, a D.C. jury convicted Percey Jordan Jr., 42, for murder, robbery and credit-card fraud. Jordan’s cousin, Michael Hamlin, 24, pleaded guilty to murder and conspiracy.
