Johnny Wactor’s Friend Organizes March in Downtown L.A. Month After Murder

Johnny Wactor‘s close friend is pressuring L.A. officials to find his murderers and hold them accountable … organizing a march through downtown to keep the late actor’s memory alive.

Micah Parker — a fellow actor and one of Johnny’s best pals — spearheaded Wednesday’s march, and we talked to him in the street  … with him telling us Johnny’s murder should be a wake-up call for the city, hoping those in power acknowledge there is a problem with crime.

TMZ broke the story … Johnny was shot and killed by a group of thieves who were trying to steal his catalytic converter … a type of theft that many Angelinos are very familiar with.

There was a solid turnout for Wednesday’s rally, which Micah says is emblematic of people being tired of going unheard.

Outside city hall, demonstrators carried signs calling for #JusticeForJohnny … and they picketed with cardboard cutouts of Johnny’s face, leaving flowers and candles at a makeshift memorial. We even talked to Johnny’s ex-fiancée, Tessa Farrell, who was in the crowd too.

Remember … Tessa spoke out against Johnny’s murder in the aftermath, and caught some heat from his family. But here, she’s incredibly sincere … not to mention, emotional.

As we first told you … Johnny’s body was cremated and his remains are being sent back to South Carolina, where his family lives.

There’ve been no arrests in the case so far … but cops are working on some leads.
