An investigation is underway after a woman’s body was found early Sunday in the Mountain Brook Athletic Complex parking lot below the high school.

The discovery was made about 4:30 a.m. in the 3600 block of Bethune Drive.

Police Chief Ted Cook on Monday said they believe they know who the victim is but are awaiting positive identification from the Jefferson County Coroner’s Office.

Investigators have issued a lookout bulletin to surrounding law enforcement agencies for a possible suspect but are not yet publicly releasing his name. Cook said the deadly shooting is believed to be domestic-related. The pair have had violent domestic incidents in the past.
