(CNN) Colorado shooting suspect James Holmes has offered to plead guilty and spend the rest of his life behind bars in exchange for avoiding the death penalty, according to court documents filed Wednesday.

Prosecutors have not accepted the offer. Previously, they had said they would make a decision on whether to seek the death penalty against the 25-year-old Holmes at a hearing April 1.

"Prior to arraignment, Mr. Holmes made an offer to the prosecution to resolve this case by pleading guilty and spending the rest of his life in prison, without any opportunity for parole," the documents read.

"If the prosecution elects not to pursue the death penalty, then it is Mr. Holmes' position that this case could be resolved on April 1."
