Emma Kerrigan

Emma Kerrigan is a serial killer who appeared in The Good Earth.

Modus Operandi
Emma targeted healthy men and found them at farmers' markets. After abducting them, she would take them to the barn on her farm and hold them captive nude, forcefeeding them a cocktail of soil additives such as gypsum and animal feed such as flax through a tube inserted into their throats and injecting it with a liquid syringe. After killing them with an axe, she would dismember the bodies and grind the parts with a wood chipper. Afterwards, she would use the bodies as fertilizer.

Profile
The UnSub is highly organized and thorough woman, likely aged 30-40. She's familiar with the rural area and is therefore probably a native or has lived there a long time. She is probably keeping her victims in isolation, which requires privacy and isolation, suggesting that she has access to some sort of land or facility that gives her this.

Initially, the BAU believed that she targeted healthy men to use for breeding.
