Four people brutally attacked and Alton man in his home after robbing him of marijuana and drug paraphernalia earlier this month, authorities said.

The four were charged last week in the Jan. 16 home invasion in the 1300 block of Pearl Street. The charges were unsealed today, after the last of the four was taken into custody.

Three men and a woman entered a home on Pearl Street to rob a 55-year-old man inside, police say. Christopher "SP" Hill, 27, took marijuana and drug paraphernalia from the victim at gunpoint, then kicked and struck the victim with a gun and a pipe wrench and stabbed him with a knife, according to court documents.

Curtis Jerome "Ghost" Wallace, 38, also kicked, struck and stabbed the victim upon entering his home, court documents say.

Both were charged with attempted first-degree murder, armed robbery and home invasion. Each was held in the Madison County Jail with bail set at $250,000 for each.

Two others — DeMarco M. Smith, 20, and Rachel M. Barnes, 24 — were charged with armed robbery and home invasion. Both are being held with bail set at $150,000 each.

The victim was taken to a hospital with injuries described as life-threatening, but he has since been released.
