Concord police received a call from the victim shortly after midnight Sunday reporting that he had been robbed and that somebody had fired shots though his front door.
The victim told police he had responded to a Craigslist ad posted by a woman named "Angel" and arranged for her to come to his house in the 4700 block of Matheson Court, Cerletti said.
When the woman arrived, they discussed money and the victim agreed to pay the woman $100 in cash.
After he put the cash on the coffee table, the woman asked for a glass of water, Cerletti said.
The man went into the kitchen to get her some water and when he returned, the cash was gone and the woman was heading for the door.
The victim confronted her and the two got into a struggle.
The women then screamed and a man with a black pistol came to help her.
When the victim saw the gun, he pushed the woman out the door and closed it behind her.
The man then fired two rounds through the door, hitting the floor, and then the pair got into a car, possibly a gray or light-colored Buick Regal, and drove away.
The victim was not injured other than a few scratches and bruises from the scuffle.
"Angel" was described as a black woman about 22 years old with brown hair, brown eyes and a light complexion. She was about 5 feet 1 inch tall and weighed about 135 pounds. She was last seen wearing a black tank top with white sequins and blue jeans.
The gunman was described as a black man in his mid-20s, about 5 feet 8 inches tall with black hair, brown eyes and a dark complexion. He was last seen wearing a black baseball cap, a black shirt, dark jeans and black gloves.
Both suspects remained outstanding Monday, Cerletti said.
