Investigators searching for a woman missing in Orange County, California, after she failed to return home from a trip to her son’s football game one week ago are focusing on a trail of trace gas near a home linked to the family.
Alfredo Ramirez Sr., the husband of 34-year-old Carlina White, said investigators found a fuel tank on Wednesday at a friend’s home about a mile from the family’s home.
No one was inside the home when investigators cordoned off the area with yellow police tape as they checked out the fuel leak, Calderon said.
Carlina White was last seen December 17 at her son’s high school football game in North Hills, about 15 miles south of Orange County, investigators said. Police have declined to comment on a possible motive in her disappearance.
Theories abound about what could have happened.
“If I had known this woman didn’t get home, I would have done everything I could to help her, absolutely,” Erika Taylor, a neighbor of the family in Costa Mesa, told CNN affiliate WESH on Thursday.
White’s family is in shock over her disappearance, CNN affiliate KABC reported. A family friend, Pilar Perez, told the station she was “scared, but most of all, she’s devastated.”
In her remarks to reporters, Calderon said there were no suspects in White’s disappearance and described her case as a missing person case. He also stressed there was no evidence pointing to foul play.
White and the suspected killer “grew up together, and they were very close,” Calderon said.
In a family news release, authorities said they were focusing their search on the late-night hours the day after she disappeared.
Investigators canvassed the neighborhood, the statement said, which was, “covered with freshly fallen snow in an effort to locate Ms. White.”
Investigators do not believe White’s whereabouts are beyond their search area, Calderon said.
