James Holmes, the suspected shooter in last week's movie theater massacre, has told his Colorado jailers he doesn't know why he's locked behind bars, the Daily News reports.
But no one at the Arapahoe County Detention Center is buying Holmes' story, a lockup worker told the News. The jailers who come in contact with Holmes, who is sequestered from other inmates, believe he's faking amnesia.
Since the 24-year-old PhD dropout was accused of killing 12 theatergoers and wounding 58 at a midnight screening of "The Dark Knight Rises" last Friday, the media has lavished attention on Holmes' odd behavior.
The suspect appeared in court on Monday with brightly dyed orange hair and made peculiar facial expressions. At times his eyes bulged and he often appeared tired.
Holmes was taken into custody after he allegedly stormed the sold-out premiere of the latest Batman film. Police have said Holmes wore riot gear, used smoke bombs and armed himself with three guns during one of the most violent shootings in American history.

Besides the shooting, Holmes outfitted his apartment with deadly boobytraps that authorities had to defuse.
While in police custody, Holmes puzzled detectives who supposedly saw him using evidence bags as puppets, according to a KMGH report.
A jail worker told the Daily News in a previous report that Holmes wanted to know how the movie ended.
His courtroom behavior combined with accounts of awkward antics behind-the-scenes raises the question of his mental condition. Experts told ABC News he could be experiencing a genuine psychotic episode or foreshadow an insanity defense from his lawyers.
A notebook apparently sent by Holmes to a psychiatrist was found Monday and contained disturbing sketches of a stick-figure attacker carrying out a killing similar to what occurred in the Aurora cinema.
College records about Holmes will be tougher to come by. An order from District Court Judge William Blair Sylvester forbids the University of Colorado from releasing information about Holmes' enrollment in a neuroscience doctoral program.
The former University of Colorado neuroscience student will be in court again on Monday. Prosecutors are expected to formally charge him then.
