KANSAS CITY, Mo. -- Authorities in Kansas City are searching for a girl they believe was abducted by a gunman who shot her grandfather, reports CBS affiliate KCTV. An Amber Alert has been issued in Kansas and Missouri for 15-year-old Brajean Sledge. Police responded to the report of a shooting Thursday at a Kansas City home, where they found Sledge's 60-year-old grandfather shot and wounded.

He was taken to an area hospital and is in serious but stable condition, the station reports.

Police say they believe the suspect, between 18 and 20 years old, may be with Sledge. He is considered armed and dangerous and Sledge is believed to be in danger, Kansas City police officer Jake Becchina told the station.

The two were last seen traveling northbound in a 2017 Kia Forte. Police say they located the vehicle abandoned Thursday in south Kansas City. Investigators were canvassing the area and processing the car for evidence.

Sledge goes by several different names, including Brajean Sweeten, Bre-Shawn, Brayshawn, and Rayshawn, the station reports. She was last seen wearing a white V-neck T-shirt and black pants, and her hair is black with a blond weave, police say. Anyone who sees her is asked to call 911.
