Lisa Showalter, 53, was arrested Wednesday at Nashville International Airport.
Andrew Waddell, 32, was also indicted on one count of first degree murder.
Jeffery Ola was shot and killed on January 6, 2001.
CENTERVILLE, Tenn. -
The ex-wife of a Hickman County man murdered nearly 13 years ago was arrested Wednesday for his death. Her son is also charged in connection to the crime.
Deputies with the Hickman County Sheriff's Office arrested Lisa Showalter, 53, at the Nashville International Airport.
She is charged with first degree murder for the execution-style killing of her then-husband, Bellevue paramedic Jeffery Ola.
Ola was returning to his home on Beach Street in Centerville on the night of January 6, 2001 when someone walked up and shot him nine times in his car.
He was on his cell phone talking to his mother at the time and his mother heard him say he had been shot and was dying.
Sheriff Randall Ward said information was recently developed that led to a grand jury indictment charging Showalter and her son, Andrew Waddell.
Waddell, 32, who was Ola's stepson at the time of the murder, was also indicted on one count of first degree murder.
He is currently serving a 15-year sentence in Mississippi for a 2003 armed robbery conviction.
Sheriff Ward told News 2 Showalter voluntarily surrendered. She drove from her home in Lincoln, Nebraska in a rental car to the airport in Nashville where deputies took her into custody.
The sheriff told News 2 he promised Ola's family he would not let the case die and the indictments of Showalter and Waddell are for them.
He said, "My heart goes out to the Ola family and I hope this arrest brings them some closure."
Showalter was booked into the Hickman County jail on $250,000 bond. Waddell is scheduled to complete his sentence in Mississippi in 2017 and Tennessee authorities have placed a hold on him to face the murder charge.
Ola's brother Gary, a corporal with the Cheatham County Sheriff's Office, expressed his gratitude to the investigators who tirelessly chased down leads.
"Every Christmas we go out to his grave, me and my sister and my mom and his kids and this year we will be fortunate to say, ‘Merry Christmas brother because justice has started and we are very pleased,'" Gary Ola told News 2, adding, "I am overwhelmed after 14 years it is coming to an end, it's just closure. My mom's health is not real good, and I've always prayed to let her see this [day]."
Gary Ola said Jeffery, his oldest brother, was his best friend and mentor.
"It's just beyond words, the whole family is grateful to everyone who played a part in this [arrest] and we're just glad," he said. "I'm overwhelmed that after 14 years it is coming to an end and it is finally over."
