Federal agents raided Sunset Mesa Funeral Directors in Montrose earlier this month and the state has shut it down for several alleged violations including cremating and embalming bodies without permission.
No charges have been filed.
The FBI on Friday set up an email address, [email protected], for people with information about the business. The agency said it would respond with a link to an online questionnaire and would interview people who may have relevant information.
Investigators said they also will test some cremains to determine if they are human.
