Durham, N.C. — Three people pleaded guilty Tuesday to second-degree murder, burglary and robbery with a dangerous weapon in a July 2006 homicide.

Christy Crittenton, of Creedmoor, and Brian Courtney Brooks and Christopher Brooks, both of Garner, pleaded guilty in the case of retired Durham businessman Edwin Knowles, 71.

Knowles was found dead in his home in Bahama, in Durham County. He had been beaten and shot.

Crittenton was sentenced to 240 to 297 months in prison, Brian Brooks to 151 to 191 months and Christopher Brooks to 132 to 168 months.

Knowles’ daughter, Edie Parra, gave Crittenton a Bible in court Tuesday and said she forgave her.

Another man, Anthony Rankins, 41, pleaded guilty to first-degree murder in the case last November.

He was sentenced to life without the possibility of parole and then two consecutive sentences of 146-185 months for armed robbery and burglary.

Authorities said the four stole jewelry, watches and money from Knowles' home.
