Verna McClain: Registered Nurse Admits To Killing Kala Marie Golden, Abducting Newborn Keegan Schuchardt [PHOTO]

Verna McClain, the 30-year-old woman charged with killing young mother Kala Marie Golden and abducting her newborn son, Keegan Schuchardt, admitted to the crime, authorities told the media.

Montgomery County District Attorney Brett Lignon said Verna McClain was charged on Wednesday, for fatally shooting Golden and taking her son. She has been charged with capital murder.

Lignon told ABC's Good Morning America that McClain told investigators that the shooting was part of a plan to kidnap a child.

She's given a full statement to the detectives with the Montgomery County Sheriff's Department, Ligon said. As part of the statement with that agency, in conjunction with the other evidence that we were able to obtain yesterday...we did charge her [McClain] in the early hours of this morning with capital murder.

Golden was reportedly standing by her pickup truck outside the pediatrician's office in Spring, Texas, on Tuesday afternoon when a car pulled up. There was a man and woman inside the car.

Good Morning America reported that an altercation took place and the woman exited the car and repeatedly shot the young mother. The woman took the baby and drove off.

Ligon said he doesn't believe that Golden was specifically targeted. Keegan was found  late Tuesday night after McClain took him to her home in Harris County.

The Associated Press reported that McClain's sister, Corina Jackson, told authorities that McClain intended to do the adoption now that she had Keegan.

McClain is being held without bail.
