The first charge has been filed accusing a 47-year-old Massachusetts man of killing a 13-year-old girl from Amesbury in May.
Carlos Rivera, of Lawrence, had faced other charges in connection with the death of Chloe Ricard, but a grand jury in Essex County indicted him Thursday on an involuntary manslaughter charge in her death, along with charges accusing him of rape and human trafficking.
All but seven of the 19 indictments brought Thursday are new charges, according to the Essex County District Attorney's Office. Rivera is now accused of human trafficking and additional rape charges, charges he will face Friday when he is arraigned.
Chloe was left at Lawrence General Hospital on May 20 and died shortly after her arrival, prosecutors have previously said.
Days later, Rivera was arrested on charges that initially included indecent assault and battery on a child under 13 and giving drugs to a minor. Later, rape and distributing cocaine to a minor were added.
Added indictments against Rivera charge him with involuntary manslaughter, four counts of aggravated rape of a child and six counts of human trafficking.
In June, prosecutors said Rivera sexually assaulted and gave cocaine to teenage girls. They also said he also indecently assaulted a 16-year-old girl at an earlier date.
But Thursday's grand jury indictment widens the number of people Rivera is alleged to have hurt. Prosecutors now say he victimized three women and and seven girls, including the two girls whom Rivera was originally charged in connection with.
According to court documents previously obtained by The Boston Globe, Rivera allegedly lured teenage girls to his apartment by offering them drugs, alcohol and money in return for sex. Prosecutors had said he may have committed sex- and drug-related crimes against "more than a dozen" other victims.
The court documents also show allegations that Rivera had over 7,000 photos of teenage girls on his phone and more than 100 pictures of girls in his bedroom.
