The 26-year-old architect was shot once in the chest on Front Street after two men grabbed for her and her mother's purses.
"He complained there was something wrong with his chest and shoulder. He said someone had assaulted him, but wouldn't say who, wouldn't mention a name," said sheriff's spokesman Joseph Blake.
A spokeswoman for Hahnemann University Hospital said Beatty was in fair condition.
Prosecutors say Beatty, a paroled felon, tried to pin the killing on acquaintances to get out of a drug debt to them. He was arrested Jan. 21 after allegedly telling police that he had tried to frame four people.
He said they had given him drugs to sell, and he smoked them instead. Using information from the news, he called 911, and said he knew where the killers could be found.
Assistant District Attorney A.J. Thomson said Beatty faces an added felony charge of hindering apprehension. "In the first 48 hours of this investigation, this man sent dozens of officers all over this city on a wild-goose chase," Thomson said. "Justice demands he stand trial."
