Neomar Lander, 17 year old student, was killed on Wednesday June 7th, 2017, in Chacao district, Caracas. What I think I know I learned from several videos and interviews made right after the event. What I saw was a skinny young man trying to approach a line of national guards placed above him on Francisco de Miranda (I think the guards were blocking marchers from turning West towards downtown Caracas).
Neomar was leading a small group of youngsters trying to go down to Libertador Avenue using the sunken access lane when two back to back explosions are heard. The next view shows Neomar lying on the ground and his friends trying to recover his body as the guard fires a volley of tear gas grenades. I can't say whether he was shot at close range with a grenade launcher (this seems to be a prevalent technique used by Maduro's guards and police), or whether he blew himself up.

The investigation will be tainted because the site was controlled by the same national guard/political police (SEBIN) unit which may have killed him. What I do know is that in most countries we don't see 17 year olds dying during protest marches being tear gassed, beaten, dragged behind motorcycles, run over, arrested, and tortured for over 60 days by a dictator who is stealing, starving the people as the outside world either ignores what is happening (just like they ignore Yemen and ignored the Rwanda genocide), or says they are "concerned" and send their best wishes.
