Kharom lodged the complaint with the court at 10 am.
The relatives want the court to conduct trial as to who killed the nine protesters at the Kok Wua Intersection on 10 April.
Kharom also asked the court to allow 19 red-shirt leaders, who have been detained, to become witnesses in the case.
The Criminal Court has yet to decide whether to proceed with the complaint.
