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.

After that, there is a five hour gap where Camou's whereabouts are unaccounted for, Hoglund said. He is not spotted again until he visited a Chase Bank ATM along Foothill Boulevard in Azusa about 2:41 p.m.
Authorities are trying to figure out what Camou did during that time and are asking for the public's help.
Camou was later seen in a video at a downtown Los Angeles bar that night rapping about killing his girlfriend and burying the body. After the chilling video surfaced, the Sheriff's Department said they were investigating the video, and on Thursday, Hoglund confirmed the man in the video was Camou.
Camou, who authorities are calling their primary and only suspect, was involved in a standoff with police, where he refused to come out of his Prius. He was arrested early July 30 after authorities shot tear gas into the vehicle.
Authorities found more blood and a "digging tool" in the suspect's vehicle after a search. Hoglund said the blood is being tested and he did not elaborate on the kind of tool that was found.
Since then, authorities have been focusing their search for Custer in the Lytle Creek and Mount Baldy areas.
Her father asked anyone who might have been in that area on July 29 and might have seen something suspicious to come forward.
“Somebody out there must have seen something, and now would be a good time to call it in," Rick Custer said Thursday. "We just want Amanda home."
Rick Custer said his daughter has an 8-year-old son who is safe with family. He added that his daughter had recently gotten a new job and was preparing to move out of town in an effort to "get away" from Camou.
Authorities still do not have a motive for Custer's disappearance, but are asking anyone with information to call 323-890-5500. Those who prefer to remain anonymous can contact Crime Stoppers at 800-222-8477.
