A pregnant woman and two children were sent to the hospital after being by a car Monday morning in Hopkinton, Massachusetts.
Hopkinton Police say the crash happened along Hayden Rowe Street around 10 a.m.
"When I got the call, it was horrible," said Chris Masters, whose 4-year-old son, Chase, was hit.
Masters's son was one of four people sent to the hospital, along with another child and the family friend that was pushing him in the stroller. Masters' wife was pushing the other child in a stroller behind her.
"When he got moved out of trauma, again he was just quiet," said Masters. "He took a little bit of a nap, but all things considered, he's doing well. We're just waiting to get some tests back."
Police say the group was walking in the crosswalk, headed to the park, when a 61-year-old woman from Hopedale stopped her car to let them pass.
That's when a 32-year-old man from Milford hit the woman's car, knocking her off the road. His car then hit the woman the children.
One driver was also sent to the hospital. Police have not specified which driver it was.
"I started crying," said Nancy Siegal who knows the families involved. "It's horrible, unacceptable and I hope whoever caused this is punished."
At the crosswalk, there are neon yellow signs in both directions that alerts drivers to the crosswalk.
"Just need to be move vigilant and be cautious," said Chief Edward Lee of Hopkinton Police. "Especially in a school zone like this, where there are pedestrians up and down this street all day long."
Jean Petani lives feet away from where it happened. She said she was asleep when the sound of sirens woke her up.
"I don't want to say I wasn't shocked, unfortunately, because I know how busy this road is with traffic," said Petani.
Masters said he hopes his son will be back home Monday night.
"Any road is a dangerous road when you're not paying attention," said Masters.
Police have not released the names of the drivers involved. No charges have been filed and police are still investigating.
"If there needs to be charges, we will certainly file them," said Lee.
