A report on the ground from the ICE shooting in Biddeford that should make every parent in this country lose their minds:
Cecelia Humiston, 22, lives on Chapel Street. She was asleep with her two-year-old son when she woke up to the sounds of a commotion on surrounding streets.

When she went to investigate, she saw what appeared to be a person lying on the ground on Pool Street.

She remembers hearing an older woman with a distressed family, yelling, “You took her dad, you took her dad!”

“They were with a little girl, she couldn't have been older than three,” Humiston said. “She was still in her Bluey pajamas.”

Humiston described law enforcement as “rude,” and said they barricaded family’s car from leaving. Another yelled at the little girl, who was trying to smell flowers.
