Friends of a Dallas man who was shot and killed are speaking out.

Joshua Tubbleville, 33, was found dead inside his Mercedes near Oak Lawn and Lemmon early Friday morning.

Police said someone shot him inside his car, which led him to crash at the Shell gas station there.

Stacy Woodward and Bob Thomas were with Tubbleville the night before he was killed.

"I don’t think there’s anything you can say to describe the way you feel when someone you’re close with, something like this happens to somebody you’re close to," said Woodward.

Thomas said it was unreal that he was picking out his friend's funeral outfit on Saturday.

"That’s hard to know that you’re picking out your friend’s, what he’s going to be buried in. You smile because you know that he’s looking down from heaven going, 'I’m really hoping you pick something good for me,'" he said.

Homicide and crime scene units visited Tubbleville’s town house looking for clues. Woodward said it’s just a matter of time before the shooter will be brought to justice.

"They have witnesses, there’s people who say, ‘I saw the guy, I came face to face with the guy. I could pick him out,'" she said.

As the investigation continues, Thomas is urging anyone with information about this tragedy to step forward and help bring closure to his loved ones.

"To have a friend die so tragically and so suddenly ... his mom and dad and his brother are suffering a lot too," he said.

Tubbleville's brother and parents are all in Houston. His brother is making funeral arrangements.
