Two psychologists concluded last summer that Drommond is competent.
He faced charges of capital aggressive murder, first-degree felony attempted aggravated murder and a class A misdemeanor, for fatally shooting Janeil and wounding her father.
A jury will sentence Drommond beginning Feb. 13, 2008. If 10 of the 12 jurors agree, Drommond will face life in prison without parole. Otherwise, he will spend 20 years to life in prison.
As part of the plea agreement the first-degree felony charge of attempted aggravated murder and the misdemeanor charge of a violation of a protective order were dropped.
