Robin Lynn Jones of Fort Smith has pleaded guilty to murder and was sentenced to 30 years in the Arkansas Department of Corrections.

Jones was 46 in December when she was charged with the murder and aggrated robbery of 67-year-old Margaret Scamardo at Scamardo’s North 39th Street residence. As part of her plea deal, Jones received 10 years probation if she is paroled following 70 percent of her sentence.

Jones’ plea agreement was filed Sept. 5 with the Sebastian County Clerk. She had been set to go to trial next month. Jones told police in her affidavit last year she got into a fight with Scamardo, hit her with a lamp and choked her with the lamp chord.

Officers were initially dispatched to Scamardo's residence to conduct a welfare check because she had not shown up for work or answered her cellphone for two days. Scamardo’s residential natural gas line was on at the time of officers’ response, and her red 2000 Nissan Frontier was missing from the residence. Jones was developed as a person of interest and agreed to go to the Fort Smith Police Department for questioning. She was arrested following the interview.
