Sex Offender Says He Was To Wed Slain Investigator

DUBLIN (CBS/AP) -- A career criminal and sex offender who was the last person to see a slain federal criminal investigator says the two planned to wed.

The woman's family says 56-year-old Randy Alana is a liar.

A reporter for the Oakland Tribune talked to Alana at the Santa Rita Jail, where he is being held on a parole violation. Alana said that he met Sandra Coke two decades ago while she investigated a murder case. He denied harming her.

Coke's family said the two dated briefly 20 years ago, but he was under court order to stay away from the investigator.

Her sister Tanya Coke said Alana is "lying and manipulating to serve his purposes."

Coke disappeared Aug. 4 after saying she was meeting someone with information about her missing dog.
