A 16-year-old Columbia youth charged in the slaying of his home tutor has been indicted on charges of rape and perverted practices in connection with her death.
Through an additional indictment, a Howard County grand jury has brought sexual assault charges against Alton Romero Young, of the 7500 block of Murray Hill Road.
The teen-ager was charged with first-degree murder in the March 25 strangulation death of Shirley Rue Mullinix, 57, of Dayton.
The new indictment, handed down May 7, alleges that Young strangled Mullinix while he was raping her and that he had sexual intercourse with her after he had killed her.
The additional charges are based on recently completed forensic tests and serological analysis, said Michael D. Rexroad, the county's supervising assistant state's attorney.
Police allege that Mullinix was killed in the Young home following an argument over his grades.Young allegedly carried the body outside, put it in the teacher's car, drove to a nearby High's store in the Village of Kings Contrivance and dumped the body down the hill, police said.
The victim's fully clothed body was discovered behind the High's store in the 7600 block of Murray Hill Road by two middle school students riding bicycles.
A bloodhound led police to a dirt path leading from behind the High's store to the Huntington Downs apartment complex on Clock Tower Lane. Young became a suspect after police found his school papers and Mullinix's wallet and other belongings in a trash bin at the complex. He was arrested March 26.
The victim's car was found two doors away from the suspect's apartment building, police said.
Mullinix had been employed by the school system for three years as a teacher for students unable to attend regular classes because of health or disciplinary problems. According to school policy, another adult must be present when home-study teachers work with individual students.
