Lindsay Newkirk received a three-year prison sentence for injecting a lethal dose of heroin into her father's arm last year.

COLUMBUS, Ohio -- A woman accused of giving her father a fatal dose of heroin last year pleaded guilty Tuesday.

Lindsay Newkirk cried as the prosecutor described the day she prepared heroin and injected into her own arm then into the arm of her father. It was drug abuse that turned deadly for the 55-year-old man.

In front of Judge Kimberly Cocroft, Newkirk pleaded guilty to involvement in the death of her father and received a three-year prison sentence.

In agreement for the 27-year-old woman's guilty plea, the prosecutor dropped the secondary charge of corrupting another with drugs in the death of Leonard Newkirk.

Leonard Newkirk was discovered dead February 13 inside a West Broad Street motel. An autopsy confirmed acute intoxication by heroin.

The prosecutor said in conversations with the woman admitted that she and her father had a drug habit.

According to the prosecutor, Linsday Newkirk said she would commonly prepare the drug and try it first before injecting heroin into her father's vein.

Judge Cocroft warned Newkirk to seek help for her addiction, saying she did not want to see her obituary in the paper.

"This is an almost unthinkable tragedy," said Cocroft. "I've seen the heroin epidemic in many forms but this is the first time I've had family members who have been so incredibly impacted. And this is a tough lesson to learn."

The prison sentence of three years was imposed with credit for the 181 days she has already served behind bars. Newkirk will also be on probation for five years after her release.
