Deleting node in linked list

Most of code works but when I try to delete last element of my list and I print it I see in its place some garbage data, what I'm doing wrong here? Could somebody point my mistake?

void DeleteClient2(struct client *temp,struct client **head)
{   struct client *prev=*head;
    struct client *current = *head;
    struct item *currentitem = (*head)->item_data,*save;
    if(temp== *head)
    {
        while(currentitem != NULL)
        {
            save = currentitem;
            currentitem = currentitem ->next;
            free(save);
        }
        free(temp);
        temp->item_data = NULL;
        (*head) = (*head)->next;
    }
    else
    if(temp->next == NULL)
    {
        while(currentitem != NULL)
        {
            save = currentitem;
            currentitem = currentitem ->next;
            free(save);
        }
        temp->item_data = NULL;
        free(temp);
    }
    else
    if(temp != *head && temp->next != NULL)
    {
        while(prev->next != temp)
        {
            prev=prev->next;
        }
        prev->next = temp->next;
        while(currentitem != NULL)
        {
            save = currentitem;
            currentitem = currentitem ->next;
            free(save);
        }
        temp->item_data = NULL;
        free(temp);
        temp=temp->next;
    }
}
