A 26-year-old West Loop woman, who was killed when two boats collided in Monroe Harbor overnight, was "the sweetest human being," her father said. Johanna H. Gregory was among 14 people aboard two boats involved in the collision, which happened a few minutes before midnight. "She had a heart of gold and was the sweetest human being and I don't understand how someone so sweet could be taken from us," Douglas Gregory told the Sun-Times through tears.Three other people were in serious-to-critical condition at area hospitals, and a fifth was in fair condition, all suffering injuries from the crash, the Chicago Fire Department said.An autopsy is scheduled for Gregory, according to the Cook County medical examiner's office. According to her father, Johanna was a pediatric occupational therapist "who treated a number of young children between six months old and 4 years old."Elizabeth Benney, a former coworker, was shocked to learn of the fatal collision.Benny worked with Gregory at EB Pediatric Resources, 633 W. Addison St., before Gregory moved on to another job about February, 2025, according to her LinkedIn profile.Gregory worked primarily with children from birth to age 3 whose families were in the Early Intervention program.“She was a skilled occupational therapist,” Benney said in an email, and she made "a significant impact on many families here in Chicago while working with us."Parents and caretakers who learned from Gregory significantly increased their child’s developmental progress, Benney added. The families in Gregory's care loved her, she said.And when Gregory left for another company, almost all of the staff gathered to wish her well, Benney said.“We’ve really missed her," Benney said.This is a developing story.
