A former Boston banker accused of being a serial rapist who held most of his victims, including 13-year-old and 14-year-old girls, at knifepoint and stabbed three of them, officials said Tuesday.
Evan Cheung, 42, was charged with multiple counts of felony rape, rape of a child and other crimes by the Suffolk County District Attorney’s Office from 2003 to 2006.
Cheung, who has addresses in Boston and suburban Quincy, was held in return for $1 million in bail after appearing in Boston Municipal Court on Tuesday, NBC Boston reported.
A spokesman for Boston-based financial services firm State Street said Tuesday that Cheung had been fired. A LinkedIn profile that appears to be of Cheung lists his position as vice president of procurement category strategy at the company.
In the first case, Cheung is accused of picking up a 13-year-old girl in Boston’s Chinatown neighborhood, the prosecutor’s office said.
He is accused of taking her to an isolated location, where officials say he raped her at knife point and stabbed her in the shoulder, the statement said.
Cheung is alleged to have picked up a 14-year-old girl from the Charles Circle area a week later. Prosecutor Ian Polumbaum alleged in court that he held a knife to her throat before raping and stabbing her twice.
Two years later, Cheung picked up a 23-year-old man near downtown Boston, the statement alleged. The prosecutor’s office said he held a knife to her throat before raping her and stabbed her repeatedly.
The prosecutor’s office said he is also accused of picking up an 18-year-old girl in the city’s North End neighborhood, placing a knife around her neck and raping her.
Cheung was arrested after authorities began an effort in April to re-investigate 100 unsolved sexual assault cases in Boston.
Polumbaum said detectives followed Cheung to a mall this year and retrieved his discarded cigarette. Polumbaum told a judge that a male DNA profile obtained from cigarettes matched genetic material taken from sexual assault kits used in the 2005 and 2006 cases.
Polumbaum said there were other “common threads” in the four cases, in which the suspect was used in a car-type attack.
Cheung’s attorney, E. Peter Parker, said in an email Wednesday that the allegations are “very old.”
“This presents complex evidence, factual and forensic issues for the prosecution, which we will aggressively challenge,” he said.
Cheung’s next court appearance is September 22.
