Richard is a cousin of Anna Rodriguez, the housekeeper working at the Walsh Family House. He first appears at the home being introduced to Brandon and Brenda by Jim. He informs them that Karla Montez will be using their address on her record to attend West Beverly Hills High School because of the gangs and drugs in Pomona.
He is later seen waiting outside Anna's home as Brandon drops her off from school, telling her that she'd better be careful. He is later seen watching her from a distance as they go on a date. When Brandon shows up to take Karla to breakfast, Richard is very stern in telling Brandon that she can't go to breakfast and secretly tells her to stay away from him, sending up a red flag with Brandon, who is untrusting of him.
He is later spotted by Dylan McKay sitting outside of the Walsh House during a party given for Chick Schneider. After Brandon has a fight with Chick, Karla leaves the party and gets into his car and goes home.
Richard is later revealed to be a prosecuting attorney in a murder case in which Karla witnessed the killing of a four year-old boy.
