  The Husband Who Programmed a Killer

  Sep 30, 202644 min

  We chronicle the tragic 2017 murder of Renata Davis, a dedicated nurse from Plaquemine, Louisiana, whose life was ended by a violent domestic conspiracy.

The narrative details how Lewis maintained simultaneous secret relationships with a girlfriend and his own mother-in-law, Esther Lacoste, who was pregnant with his child at the time of the crime. Evidence suggests Lewis weaponized Esther’s mental instability and paranoia, manipulating her into physically committing the homicide to resolve his own marital and financial burdens. Following a tense police standoff that ended in Esther’s suicide, Lewis was eventually convicted of conspiracy to commit murder and sentenced to life in prison. Ultimately, the sources examine the profound betrayal and complex manipulation that destroyed a family and took the life of an innocent woman.

Key evidence, such as incriminating phone records and forensic data, eventually linked the siblings to the meticulously planned killing.
