Lana Sue Clayton, of South Carolina, has been arrested for allegedly poisoning her husband over a period of three days in July.
On Friday, detectives in York County arrested and charged Lana with Murder and Unlawful Malicious Tampering of Food as it relates to her husband, Stephen Delvalle Clayton.
In the press release, the sheriff’s office also shared that Stephen, 64, died on July 21 at their home, and that “the investigation autopsy toxicology tests discovered poisonous levels of Tetrahydrozoline in the body of the victim.” The chemical is frequently used in eye drops.
“Lana Clayton admitted to investigators she administered the substance to Stephen Clayton without his knowledge,” the sheriff’s office continued, adding that the case is still under investigation.
Stephen, who founded a nation-wide company called Physical Therapy Resource before retiring, was found in the foyer of the property after appearing to have fallen down the stairs, The Herald reported.
The York County Sheriff’s Office did not immediately respond to PEOPLE’s request for comment.
Prior to her arrest — and before the results from the autopsy test were revealed — a funeral was held for Stephen on Aug. 4 in the backyard of the property where he died, neighbors of the couple told WSOC-TV.
