(CBS/WBBM) CHICAGO, Il. - Authorities say a Chicago police officer was killed by her 15-year-old grandson after she caught him skipping school.

The off-duty Chicago officer, Hester Scott, 55, was pronounced dead in her home on Friday after police say she was fatally beaten and stabbed by the grandson she had adopted.

Keshawn Perkins, 15, was charged as an adult with one count of first-degree murder and one count of armed robbery, reports CBS station WBBM. A judge ordered him held without bond on Sunday.

Perkins reportedly decided to skip school and go to sleep in the basement. Investigators say that when Scott came down and started yelling at him Perkins allegedly stabbed her with a kitchen knife and struck her on the head with a lamp. Police say Perkins admitted doing this "until she shut up."

The boy then allegedly wrapped her body in a blanket and dragged her to a catch basin in the back yard. He ran away after taking her blood-soaked purse.

Prosecutors said someone called 911 after seeing the front door to her home open, and when police arrived, neighbors brought Perkins to them. They say that two bloody knives were found at the scene, and that Perkins told police where her body was, and where he left his bloody clothing after the murder. The medical examiner's office declared her death a homicide.

Police say Scott served as a police officer for 25 years and was off-duty at the time.

If convicted, her grandson faces a minimum life sentence because the victim was a police officer. The investigation is ongoing.
