After a 59-year-old woman suffered third-degree burns Wednesday evening when a man tossed an acid-like liquid in her face in Sunnyside, police are searching for the suspect.

The attack took place at 5:20 p.m. outside of 33-02 Skillman Ave., near the intersection of 34th Street and 43rd Avenue, police said.

The victim, who media reports said is Alexandra Dyer, was getting into her car when a male called out to her from behind. When she turned around, the NYPD said, he splashed an “unknown substance” into her face.

The suspect is described as an adult African-American male standing around 5 feet, 8 inches tall with black hair. He is believed to be around 30 years old and was last seen wearing a black T-shirt, black shorts and white sneakers.

FDNY officials said Thursday that the substance was believed to be a caustic acid-like mixture and that the victim was transported to the Burn Center at New York-Presbyterian/Weill Cornell Medical Center in Manhattan.

Dyer, a St. Albans resident, real estate broker and ordained priest with the group Roman Catholic Womenpriests, recently was also the executive director of the Queens Historical Society. She was appointed in January but had left the position around a month ago, according to officials at the historical society.

Calls made to Dyer’s home Monday were not immediately successful. Dyer is also the executive director of the Healing Arts Initiative, Inc., a nonprofit organization located at the address of Wednesday’s attack.

An employee at Healing Arts said Thursday that staff are declining to comment on the situation.

Claudia, of C & J Picture Frames, next door to the organization, said she was “shocked” to hear of the incident.

“Usually it’s very quiet and peaceful,” Claudia, who did not give her last name, said of the neighborhood, adding that there’s always cars parked but it’s “a safe stretch.”
