A woman who authorities said confessed to fatally shooting her two young daughters and burying them in a rock pit was charged Monday with two counts of aggravated murder (search).

Prosecutors will have a month to decide whether to seek the death penalty for Charlene Dorcy (search), 39, after she enters a plea at a hearing on Thursday. Her bail was set at $1 million.

Dorcy called 911 from a pay phone and confessed to the killings Saturday, just hours after she said she drove 2-year-old Brittney and 4-year-old Jessica about 80 miles to Gifford Pinchot National Forest (search) and shot them, said Sheriff Dave Brown.

She answered the judge's questions in monotone during a brief court hearing Monday.

Asked if she understood the charges against her, she said "yes" softly, but piped up when asked the proper spelling of her younger daughter's name. "It's 'n-e-y.' Not 'a-n-y,"' she said, correcting the court docket, in which the name appeared incorrectly as "Brittany."

Her public defender, Robert Lewis, declined to comment after the hearing.

Prosecutor Peter Banks said authorities had not recovered a murder weapon. A warrant was issued to search Dorcy's car.

Dorcy's husband, Robert Dorsey, declined to comment after the hearing.
