Surveillance tapes from the two Wal-Marts showed a large, burgundy pickup truck that also may have been spotted on tapes recorded three months ago near where Dubois disappeared, The San Diego Union-Tribune said.
San Diego police immediately contacted Escondido detectives when they saw a burgundy pickup truck pop up in the Wal-Mart surveillance tapes, Escondido police Lt. Bob Benton told the newspaper.
No suspect has been named or arrested in any of the cases.
The man molested two girls, a 5-and 6-year-old, in separate incidents. On April 1, a little girl was abused at the Wal-Mart at College Grove, and the other on May 17 at the Wal-Mart on Kearny Mesa. Neither girl was seriously injured, according to the newspaper.
In those two cases, surveillance tapes showed a 25-to 30-year old, 6-foot-tall white man who drove what appeared to be a burgundy, four-door, full-sized truck with a silver or chrome storage box in the bed, the newspaper stated. The model is believed to be between 1998 and 2006.
In the Dubois case, a surveillance tape from a school-bus maintenance yard recorded a pickup entering the maintenance parking lot at 7:10 a.m. around the time she disappeared Feb. 13. The truck left 3 minutes later.
That burgundy truck was a newer model, full-sized, four-door maroon or burgundy truck with a crew cab. It was equipped with chrome bed rails or tie-down rails with chrome running boards and wheels, the newspaper reported.
But the appearance of the truck at College Grove and Kearny Mesa was slightly different, police said. The color of the pickup truck in those incidents was a "definite match," but the truck in the other cases is missing some of the customization spotted at Escondido, Benton told the newspaper.
But he added that there's a possibility the suspect "may have taken some things off" the truck.
