A family is grieving the loss of a retired Dallas police officer.
Robert Crider, 57, of Farmersville, was killed in a head-on crash in Collin County Sunday.
He was driving home on Highway 78, a road where five people have died in crashes in just the past three months.
The man who authorities believe caused Sunday's crash, 28-year-old Anastacio Rosas, also died in the collision.
As the investigation began into the cause of the crash, so did the search for Crider's dog, who was in his car at the time but ran off after the crash.
A picture of "Penny," a 3-year-old Vizsla, was posted online by a family friend and shared hundreds of times on social media.
Penny was spotted Tuesday. Robert Crider Sr., the victim's father, said Penny had returned to the site of the crash.

"In the Crider family, it's not four people living together in the same house, it's a family, and a dog becomes part of your family," Robert Crider Sr. said.
The Department of Public Safety said Rosas crossed into oncoming traffic and hit Robert Crider's Cadillac head-on.
Robert Crider's girlfriend, who was in the car, remains hospitalized.
Nevada, Texas, firefighter Peter Hacking and his two small children died in a wreck not far away on Highway 78 in March.
"It hits so close to home for us. Peter and Grayson and Ellie lost their lives on this road. Another family lost their family members on this road. It's particularly frustrating for those purposes," Nevada Fire Department spokesperson Amy Cortez said.
Construction on Highway 78 is a concern for many residents who use it everyday.
The stretch of road where Robert Crider died was recently resurfaced, but the center lines were not added until Monday, a day after the crash.
The Texas Department of Transportation said wet weather kept its crews from painting them on sooner.
Investigators are still working to determine what caused Rosas to cross into the oncoming lane.
