James Holmes -- Victims Families Outraged Apartment Is Being Rented

Victims of James Holmes' murderous rampage are anguished and angry that the apartment he turned into a death trap is being rented again.

We spoke with a number of families after breaking the story that the apartment -- which Holmes booby trapped with 30 grenades and 10 gallons of gasoline with the intent of killing cops -- is on the market, and they feel victimized again and disrespected.

Bill Hoover -- whose grandson A.J. Boik was gunned down by the Aurora shooter -- says, "The place should be burned down or bulldozed."

The landlord is asking $850 a month, boasting the 650 square foot 1 bedroom/1 bathroom unit is completely renovated and furnished. There's no mention about the previous tenant.

Hoover adds, "He [Holmes] is the epitome of evil and what went on in that building was horrendous ... I don't think anyone would want to stay there if they knew the evil acts that were done."

A member of another victim's family says, "There needs to be a sign saying a worthless killer lived here."

Still, we gotta ask ...
