A Fair Oaks man was arrested in connection with a deadly hit-and-run in West Sacramento that left two teenagers dead, West Sacramento police said on Sunday.

The hit-and-run happened on Saturday night on Jefferson Boulevard.

Police said two female victims were found at the scene, and that it was determined that a hit-and-run had taken place. In coordination with Vacaville police, officers found and arrested a suspect.

West Sacramento Police identified the suspect as 71-year-old David Alison Walker, of Fair Oaks.

CBS Sacramento spoke with the grandfather of one of the victims, who identified their loved one as 17-year-old Jaea Chapman.

"Jaea is dead," said Jaea's grandfather, Jerel Todd. "And that's the three words that just ripped my heart right out of my chest."

On Monday, the Yolo County Coroner's Office officially identified Jaea as one of the victims, with the other victim being 17-year-old Layla Chrissa Clemons. 

Todd was creating a memorial beside the road where his oldest grandchild, Jaea, and her friend were killed. He was just celebrating Jaea's graduation from Natomas High School months ago.

"God has a plan for all of us," Todd said. "When your ticket is up, when your ticket is up, and my granddaughter's ticket was up."

Todd said Jaea and her friend were riding on a bike and took Jefferson Boulevard as a shortcut to a relative's house when a car came crashing into them in the dark of night. It was not until the next morning that police arrested Walker.

"Unfortunately, this isn't the only tragedy that's occurred there," said Jeannette Carpenter, who lives nearby.

Carpenter said several years ago, there was another car that hit and killed a father and son who were biking on a similar stretch of the rural road.

There are zero pedestrian lanes or lights, and neighbors said cars are constantly speeding anyway.

"We spend a lot of money on our tax dollars, so let's do something about it," Carpenter said.

Just two days ago, Todd said he called Jaea and told her he loved her. He had no idea those would be the last words he spoke to her, but he had harsh words for the accused driver.

"You're going to have to pay for this," Todd said. "Because you took two lives, and you didn't stop to administer any help to these beautiful little girls. I hope your conscience is eating you alive."

Todd said his oldest child died at the age of 17 and now his oldest grandchild has died at 17.

West Sacramento Mayor Martha Guerrero issued a statement following the deadly incident.
