A paramedic in the US is accused of using eye drops to kill his wife.

Joshua Lee Hunsucker, 35, faces charges of first-degree murder over the death of mother-of-two and school worker Stacy Robinson in North Carolina.

Prosecutors said Ms Robinson’s body contained a suspicious amount of an ingredient found in eye drops that can cause heart failure, according to WCNC.

She died on 23 September 2018, but her mother later claimed Mr Hunsucker had committed insurance fraud by receiving payouts worth $250,000.

He had not allowed an autopsy before Ms Robinson’s cremation, but a blood sample had been preserved because of her wish to make an organ donation, the Shelby Star reported.

After investigators pulled him in for questioning, they got enough information to arrest him.

“I don’t know that he would characterise it as a confession, but it certainly approached that level,” said Jordan Green, a lawyer for the North Carolina Department of Insurance.

Mr Hunsucker’s lawyer said he “strenuously opposed” the allegations and he had no criminal record.

Atrium Health, the company he worked for, confirmed he was no longer employed by them.
