Dragnet (1951)

Local businessman John Keith Jarrett disappears and evidence of suicide is discovered. Friday and Smith check on the surviving members of his family and find them not the least concerned about their father's death, with his son a tennis bum, his daughter promiscuous, and his wife drunken. The case gets even murkier when a report comes in of a traffic incident upstate involving a camper in which the driver was using Jarrett's license.
