ARVADA - A local company who specializes in cremating veterans made an awful mistake on Monday.

A family from Arvada held a funeral at Fort Logan National Cemetery Monday morning to bury a beloved Vietnam airman. Sadly, things didn't go as planned.

All Veterans Funeral and Cremation was supposed to return the remains of Amado Sanchez Jr. on Friday. But when the family tried picking them up, the company told the family the ashes weren't ready.

Monday morning, the family tried picking up the ashes again, but the family says the company gave them the same excuse.

"I'm very disappointed with this company. Very disappointed," Sanchez's niece Stephanie Vigil said.

The company didn't respond to the family until 9NEWS called them.

A spokesperson from All Veterans Funeral and Cremation said there was a human error and an employee lost Sanchez's death certificate.

"Makes you sad that he didn't get the respect he deserved," Vigil said.

In a written statement to 9NEWS, a company spokesperson said the following:

"We here at All Veterans serve hundreds of families every year and we feel extremely horrible about the events that have occurred today. This is simply a case of human error to which we have taken immediate action to correct, and have taken every precaution to make sure that something like this will never happen again," said Sherri Richardson with All Veterans Funeral and Cremation.

The company said it will deliver the ashes to the family personally on Tuesday.

"He was not respected in the correct way," Vigil said.
