The Scot, in his first spell as Reds boss, was in charge of the side for the FA Cup semi-final against Nottingham Forest on April 15, 1989 at Sheffield Wednesday's ground when 96 supporters died.
Dalglish was heavily involved in supporting the families in the aftermath of the tragedy and attending numerous funerals - including four in one day.
It ultimately took its toll as he quit Anfield 21 months later with the emotional stress being a significant factor in his decision to walk away from the club.
"Very positive outcome. 23 yrs waiting for the truth next step justice," Dalglish wrote on Twitter.
