Ncediswa Mkenkcele, 42, was on trial for the January and February 2015 assaults on Hope Shepherd at Berea’s Lily Kirchmann Complex.
The assaults were captured on a hidden camera set up in a TV set placed in Shepherd’s room by her daughter, Bernice Robertson.
Presiding magistrate Ignatius Kitching said in his judgment that Mkenkcele’s actions had haunted Shepherd long after she had been moved from the old age home.
“Once [Shepherd’s daughters Deanne Guild and Robertson] had moved their mother from the establishment, they would notice their mother would sometimes raise her arms in an apparent attempt to defend herself whenever they approached her,” Kitching said.
