Suspected Gunman in Lehigh Valley Teen Girl's Killing, Shooting of 2 Others Surrenders to Police

Antwan Washington, 36, faces homicide charges in the death of 16-year-old Carolina Monsanto and shooting of 2 others

The man suspected of killing a teenage girl and shooting two others, including a woman he was dating, in a triple shooting in the Lehigh Valley Tuesday night surrendered to police late Thursday.

Antwan Washington turned himself into Allentown police around 8:30 p.m., police said.

Washington couldn't comment on his arrest since he was held on criminal homicide charges without bail at Lehigh County jail.

Carolina Monsanto, 16, was visiting a home along the 500 block of West Harrison Street in Allentown, Pennsylvania, around 5:15 p.m. Tuesday when a gunman opened fire. Monsanto died a short time later from multiple gunshot wounds to the body. 

A 31-year-old woman and a 19-year-old man, also struck in the shooting, were hospitalized in stable condition.

Allentown police identified the homicide suspect as Washington. Washington and the 31-year-old woman were involved in a relationship, investigators said.

Loved ones remembered Carolina as a student athlete at Dieruff High School who worked multiple jobs to help with family expenses.

"This girl was just a go-getter," Jessie Severino, a family friend, said. "She worked three jobs. She was a tremendous athlete. She did field hockey and she did track and field as well."

Monsanto would have turned 17 on Aug. 20. But instead of preparing for her birthday party, her family planned her funeral. Her father Ambiorix Monsanto shared words he wished he could say to his daughter one last time.

"I love you and I'll always have you in my heart," he said.
