Cassandra - How to remove a dead node

Cassandra version 1.2.9. Five node cluster, but one of the nodes is down with hardware failure and repair/replacement ETA is unknown. I want to decommission/remove the down node (the notifications are cluttering all logs). nodetool removenode seems to be perfect, except it requires a host ID. The down node has no host ID (listed as null in status):

It appears that removetoken is no longer an option for nodetool.

What is the proper way to remove this dead node?

The question is for older version of cassandra. But the official solution should apply for any version of cassandra - https://docs.datastax.com/en/cassandra/3.0/cassandra/operations/opsGossipPurge.html

The steps there basically tells to stop the cluster, delete the sstables related to peering, clear the gossip state and restart the cluster; which makes sense.
