A Florida woman is accused of pouring acid onto a man while he was in bed in what authorities called a domestic and likely “premeditated” attack.

Chuanying He, 50, has been charged with attempted first-degree murder and aggravated battery, the New Port Richey Police Department said in a news release. She was arrested and booked into the Pasco County Jail.

Investigators believe He “intentionally poured acid onto the victim while he was in bed.” They did not reveal the relationship between the suspect and victim — only describing the case as a “domestic” incident.

According to authorities, it was He who alerted them to what had happened.

“Following the attack, the defendant barricaded the bedroom door and called 911 to report the incident,” officers said, adding that “evidence gathered during the investigation indicates the act was premeditated.”

The police department was called at about 5 p.m. on Thursday to a home on the 4500 block of Slippery Rock Road in New Port Richey. When officers arrived and stepped inside, they found a man “suffering from severe chemical burns.”

He was airlifted to Tampa General Hospital, where he remained in critical condition at the time of the police department’s press release on Friday. Officers arrested the woman “without further incident” and said it appeared the attack was isolated to the two people involved.

New Port Richey is a city of about 20,000 people located in the Tampa Bay area on Florida’s west coast.
