An accused serial killer pleaded guilty Monday to killing four additional people after being convicted of killing a man in 1997.
Robert Rembert entered a guilty plea in the Cuyahoga County Court of Common Pleas Monday on the first day of his trial for the killings of Rena Mae Payne in May of 1997, Kimberly D. Hall in June of 2015, and Morgan Nietzel and Jerry Rembert in September of 2015. Rembert pleaded guilty to two counts of aggravated murder and two counts of voluntary manslaughter, court officials confirmed.
Rembert is scheduled to be sentenced Tuesday morning.
In December of 1997, Rembert was convicted of voluntary manslaughter and sentenced to six years in prison for the death of Dadren Lewis in a Cleveland parking lot.
According to the prosecutor's office, 47-year-old Payne was Rembert's first victim. An RTA employee discovered Payne's body in an employee restroom on May 15, 1997. Rembert reportedly worked as an RTA driver at the time of the murder.
On June 10 of 2015, 31-year-old Hall's body was found near an open field by two passing workers.
The prosecutor's office said DNA evidence found on Payne and Hall's bodies matched Rembert.
On Sept. 20, 2015, Nietzel, 26, and Jerry Rembert, 52, were found dead with gunshot wounds to their heads in their home on East 140th Street. The prosecutor's office said Rembert Jr. was living with them at the time.
