Billy Chemirmir

Billy Kipkorir Chemirmir was born in Kabonyony village, a suburb of Eldama Ravine, as one of 29 children. His father, Joel Chemirmir, was a long-serving Lembus chief and prosperous farmer, and his mother was the second of Joel's three wives. Chemirmir was raised in Solai and returned to his hometown after finishing high school in Nakuru to live with his maternal grandmother. He was described as an introverted loner, but also remembered for his generosity to fellow villagers. Due to problems with alcoholism, his sisters arranged for him and two brothers to emigrate to the United States in 2003. He was trained as a caregiver at a senior living agency co-owned by his family in North Texas and received permanent residency status with a green card. Chemirmir cut ties with his family a few years after his immigration, claiming he wanted to freelance as an in-home caregiver, supplementing his income by working as a car salesman. In 2004, he married a woman in Denton County, but the couple divorced in October 2006, as his then-wife complained that Chemirmir left her and could not be found through his family or employers. Prior criminal record Chemirmir had convictions for driving under the influence in Addison and Dallas in 2010 and 2011, receiving fines and short custodial sentences. In July 2012, Chemirmir was arrested for assault on a female companion. He had repeatedly kicked and punched her as well as beaten her with a pot and later stabbed a knife into a chair. He received a 70-day jail sentence after pleading no contest. In 2016, Chemirmir was twice caught trespassing at Edgemere Retirement Community, both times giving the name Benjamin Koitaba. During the second arrest in July 2016, he provided identification for both his real name and the Koitaba alias. Chemirmir again pled no contest and received a 70-day sentence, being released after serving 12 days for good behavior. Police later considered three deaths at the facility as possibly linked to Chemirmir. ==Murders==

Chemirmir was accused of posing as a medical professional or maintenance person and gaining access to the properties of at least twenty-one elderly people. Arrest On March 19, 2018, 91-year-old Mary Annis Bartel (née Crawford), a resident of Preston Place Retirement Community in Plano, Texas, told police that Chemirmir had attempted to smother her with a pillow the day before, telling her "Go to the bed. Don't fight me". Bartel lost consciousness during the attack and after her assailant left the apartment, a neighbor found her and alerted the authorities. Through Bartel's description, Chemirmir was arrested at his home the following day on March 20. Officers had seen Chemirmir discard a jewelry box in a dumpster before entering, and an examination of the item led police to a final victim, 81-year-old Lu Thi Harris (née Vang), who was found dead in her home the same evening. Bartel and Frisco resident Kay Lawson are the only known surviving victims. == Chronology ==

Police categorized the deaths linked to Chemirmir as first taking place solely in Dallas through mid-late 2016 and again through late 2017 to early 2018, broadening out to the counties of Collin and Denton. Twenty-two of the victims were killed while two survived. The majority of victims were smothered with pillows while at least one died from blunt force trauma to the head. All but one were female.
