If a person is missing for several years, some Hindu communities presume the person to be dead and perform the Hindu rituals that are performed for the dead. By most Hindu communities when a person is missing for 12 years, the death of the person is assumed by relatives. The rituals are performed after 12 years. Since the physical body of the person is not available – a body is made using Durva or Kusha Grass. This is then burnt on a pyre. Symbolically, now the person is dead for the family. Rest of the Shradh rituals are then followed as per general rules. Some communities do not perform the burning of durva or kusha grass. Instead the directly do the Shradh ceremony. It must be noted that such extreme step of performing Shradh for missing person is only taken by the family when the person missing is very old or the family is sure that the person has no chance of surviving.
