His legal appeals’ cost at this point is unknown.

Tim Jones Jr. awaits execution on Death Row for killing his 5 small children in their Red Bank home.

Mandatory appeals for 10 years or more will cost taxpayers even more.

The SC Commission of Indigent Defense has paid $509,000 so far for his defense, the bulk for expert witnesses not including travel and court testimony.

One expert, Dr. Bhushan Agharkar, said in court he charged $25,000 plus expenses to research Jones’ case. He said he cut the state a deal at $400 an hour.

A Lexington County jury found Jones guilty and sentenced him to death for killing his 5 children — Merah, 8; Elias, 7; Nahtahn, 6; Gabriel, 2 and Elaine Abigail, 1 — Aug. 28, 2014.

He pleaded not guilty by reason of insanity.

The jury didn’t agree.

Witnesses said Jones physically and mentally abused his children, fed them poorly and kept them filthy.

The SC Commission of Indigent Defense, paid by state taxpayers, has spent $509,000, according to Hervery B.O. Young, Deputy Director and General Counsel.

He said more bills are due but declined to reveal cost due to a gag order from Judge Eugene Griffith.

The Chronicle has asked for a copy of the gag order.

The Lexington County Sheriff’s Office said it cost $8,713.44 to house Jones for 144 days at the jail.

11th Circuit Solicitor Rick Hubbard said his office spent $34,725.49 for the trial.

Lexington County Clerk of Court Lisa Comer told us her office spent $38,599.62 including $15,881.44 for jury pay, $8,409.77 for rental vans, $8,683.37 for meals and snacks, $325 for postage, $556.54 for office supplies and $4,743.50 for 155,550 paperwork copies.
