NATICK (CBS) — Authorities are reaching out to the public for help as they continue to investigate a Natick hit-and-run crash that left a husband and wife with horrific injuries. Kimberly Gunner, 51, is still in serious condition in the ICU while husband Andy Colbert, 39, continues his “painful” recovery from home, their family said Thursday.

“You can run, but you can’t hide,” said Gunner’s cousin Tony Catlin.

The couple was walking on a sidewalk along Washington Avenue near Summer Street on the evening of August 18 when they were hit by a pickup truck, Middlesex District Attorney Marian Ryan said. Investigators have seized the suspect pickup truck and are reviewing surveillance video, but no arrests have been made and now they’re seeking more information from the public.

Catlin is pleading for the driver to come forward. “Do the right thing, have a conscience and step forward, and, you know, do what’s right,” Catlin said.

Anyone who may have seen the dark blue, four-door Chevy Silverado is asked to call Natick police at 508-647-9500. The pickup truck may have been in the area of Sherborn or Holliston in the early evening. Police are also looking to talk to drivers of a tan or brown SUV and a black car that may have been traveling in the Washington Avenue area and were in contact with the pickup truck driver before the crash.

“She had four fractures in her jaw bone, so she had to have her jaw bone reconstructed. Her arm was shattered, and one of her legs is very shattered,” said Catlin. “She’s intubated. Heavily sedated, so she’s not talking, but she’s here with us.”

A GoFundMe page has raised around $120,000 to help with medical expenses.

“In the midst of such an inhumane and evil tragedy caused by a few, there is an overwhelming outpouring of love and humanity by so many,” the family said in a statement.
