A man accused of killing his ex-girlfriend and hiding her body at his grandfather’s home was indicted on murder charges, The DeKalb County District Attorney’s office said.

On Tuesday, a DeKalb County grand jury formally charged Sincere Brown with malice murder, felony murder, aggravated assault and concealing the death of another.

Brown, 18, allegedly stabbed ex-girlfriend India Chapman eight times on Aug. 31 before wrapping her body in a comforter and placing it in a storage container, which DeKalb police say was then hidden in a shed at his grandfather’s Stone Mountain home.

Chapman’s family said the two remained friends after the 17-year-old broke up with him and began a relationship with someone else.

While a motive has not been released in the killing, members of Chapman’s family previously told The Atlanta Journal-Constitution they felt Brown did not handle the break up well.

A Sept. 25 preliminary hearing revealed key details, including why the two met that night and when Chapman was killed, that were largely unknown.

Chapman’s aunt Kiante Hill previously told The AJC the teen was still at home when her mother’s nurse left about 9 p.m on Aug. 30.

Hill said the girl and her brother left the home about 9:30 p.m. to go to the store. The two came back and were supposed to be in bed, Hill said.

The nurse came back the next day and noticed Chapman wasn’t home.

DeKalb police said Brown spent the night at a friend’s home before the fatal stabbing. It is not known when he and Chapman met that evening.

At 5:30 a.m. — roughly eight hours since Chapman was last seen — DeKalb police said Brown called his mother to tell her “(he) hurt India.”

It is not known what time Chapman was killed or when Brown told his mother and grandfather where her body was hidden.

During a search of the grandfather’s home, police said they found two knives believed to be used in the crime, bloody clothes in a washer and a pool of blood next to Brown’s bed and on the bedroom door. A bloody rag was also found in a trash can.

Brown remains in the DeKalb County jail and has an arraignment hearing scheduled for 9 a.m. on Jan. 7.
