James Holmes was formally charged with 24 counts of murder and 116 counts of attempted murder Monday for the shooting rampage in a Colorado movie theater, CBS News said.
Holmes did not enter a plea and did not react as the judge read the charges against him, the New York Times said.
Court papers revealed Holmes had been seeing a psychiatrist. His public defenders could avoid a trial by arguing that his is not mentally competent to stand trial, CBS News said.
Holmes sent a package to his psychiatrist prior to the shootings. She did not receive the package and police have taken it but are not saying what it contains, the New York Times said.
