The shooting happened on Bowdoin Street near Quincy Street late Sunday afternoon.
The 7-year-old boy, identified as Divan Silva of Brockton, was riding his bicycle when he was shot, according to Boston Police Superintendent in Chief William Gross. Silva was on his bike outside a barbershop, near his grandmother's house, and police believe the shooter may have intended to shoot someone standing in the doorway.
He was rushed to Boston Children's Hospital and was in the intensive care unit Sunday night after being shot in the buttocks. His condition was upgraded from serious to fair on Monday afternoon. Doctors are hoping to start rehabilitation and have Divan home as early as Wednesday.
Yefry Ciprian was inside the barbershop working when he heard gunfire. He took video of the scene just moments after the boy was shot, as police officers scooped him up off the bloody sidewalk.
Divan's aunt, Jennifer Frederico, said he was talking to his mother before he was taken away in an ambulance.
"He liked to be on the street playing with his brother and friends," said Angela Frederico, another aunt. "He's very friendly."
The other victim's head was grazed by a bullet. That person is 20 years old, police said.
Divan's family said they do not know the other victim, whose name has not been released. The barber says he was waiting to get his hair cut.
"It's not fair at all not to my nephew, not to other kids that are on the street," Angela Frederico said.
Divan's uncle Erico Frederico had a message for the person who shot his nephew.
"What they did was wrong, that's all I want them to know," he said.
Police said the suspect is a light-skinned male, approximately 5'7" and around 17 years old. He was last seen wearing tan pants and a red hoodie.
A black and white car was seen leaving the scene right after the shooting.
