Authorities on Thursday provided a timeline of whereabouts for a man believed to have kidnapped his girlfriend in Monrovia more than a week ago amid the ongoing search for the victim.

Amanda Custer was last seen July 29 and her boyfriend, Robert Camou, has been arrested, but not charged in connection with the disappearance. Custer’s father pleaded with the public to come forward with any information that might help authorities find his daughter.

Custer, 31, and Camou, 27, were involved in an altercation at a home in Monrovia about 8:15 a.m. that day. Authorities found evidence of an assault and blood in the bedroom, Los Angeles County Sheriff’s Lt. Scott Hoglund said during a news conference.

Witnesses also reported seeing Camou put Custer’s “lifeless” body in the back of his gray Prius, Hoglund said.

Authorities were able to trace some of Camou’s steps using an electronic monitoring device he was wearing in connection with an assault case.

Camou traveled east and stopped at a Del Taco along Foothill Boulevard in Glendora about 8:32 a.m., Hoglund said. About five minutes later, he visited a Shell gas station also on Foothill where he bought cigarettes.

About 8:56 a.m., Camou was seen in the Claremont area on Baseline Road and Padua Avenue, Hoglund said. From there, he continued east and went to an Arco station along Sierra Avenue in Fontana about 9:27 a.m.

The Sheriff’s Department on Thursday also released surveillance video of Camou captured during that day.
