Responding officers say when they arrived at the Cherokee Village residence, Collins  who reeked of alcohol and had blood on her face, “was not making any sense in answering questions or making statements, ” police said.
Collins was arrested and charged her with aggravated assault and abuse to an impaired and endangered person, Arkansas Online reports.
She has yet to be charged with murder since prosecutors are still waiting for her blood sample results from the state crime lab.
Henry Boyce, the prosecuting attorney for Sharp County, called the case “horrific and tragic.”
Collins was taken to White River Medical Center’s Cherokee Village complex for an examination. Police requested that medical personnel draw blood from Collins to “see what intoxicants were in her system,” a search warrant granted by District Judge Mark Johnson said.
Scott Sandefur told police he hired Collins to care for his mother. Authorities have not established how long Collins worked for Sandefur or whether she was hired through a caretaking service or directly.
Police arrested Collins May 12 charged her with aggravated assault and abuse to an impaired and endangered person. Collins was held in the Sharp County jail in Ash Flat in lieu of $50,000 bond.
Authorities sent Collins’ blood sample to the state Crime Laboratory in Little Rock and are waiting for results, and  sent Sandefur’s body to the Crime Lab for an autopsy.
“Without question, I have to reconsider all of the evidence to determine if murder was committed,” Boyce said Friday.
“Up until [Thursday], we were in the process of reviewing witnesses’ statements, photographs and medical records concerning the treatment of the victim,” Boyce said. “In light of [victim’s] death, we have to reassess our previous consideration. If we find facts that lead us to conclude she died of these injuries, we will charge [Collins] with murder.”
