David Jack-Emmings is the first Bounty Hunt in the Jack the Ripper DLC: Evie captures a violent procurer who kidnaps country girls for Lady O's brothels, and hands him to Inspector Abberline alive.
Find the target talking with his cronies; he is boasting that he is finishing what the Ripper started. Sneak up, kidnap him and get him to the rendezvous where Abberline waits.
Abberline thanks Evie for getting another dangerous man off the streets if you deliver him alive. Bring a body and he asks what use a dead man is to him.
He supplies women to Lady O's London brothels, taking girls from their homes in the countryside and selling them into the city's houses. That puts him inside the network that kept Owers' brothels full and, through the women's spying, kept the Ripper informed.
A former pugilist with a violent record is a poor match for a straight fight when the bounty has to arrive breathing. Sneaking up behind him and kidnapping him skips the brawl altogether.
Abberline has used the Fryes this way since 1868, when he first gave the twins names of gang members to bring back to him quietly. In 1888 he asks the same of Evie.
John Pizer
John Pizer is the first Carriage of Justice activity in the Jack the Ripper DLC: Evie drives this real-life suspect, nicknamed 'Leather Apron', to Scotland Yard so Abberline can question him, while people try to stop the carriage.
Robert Donston Stephenson
Robert Donston Stephenson is the last Carriage of Justice activity in the Jack the Ripper DLC: Evie delivers a writer who blamed the murders on black magic, and who had admitted himself to the London Hospital, to Scotland Yard for questioning.
Seweryn Klosowski
Seweryn Klosowski is the second Carriage of Justice activity in the Jack the Ripper DLC: Evie escorts a Polish barber living in Whitechapel, later known as a poisoner, to Scotland Yard while a mob convinced he is the Ripper chases them.
Autumn of Terror
Autumn of Terror is the second Jack the Ripper memory: Evie Frye arrives at Scotland Yard in October 1888, learns from Inspector Abberline that Jacob is missing, and rides with him to Whitechapel to investigate the first murder scene.
