Christchurch mosque shootings - A message for peace: Please don't let my sister die in vain

The brother of a West Auckland victim of the Christchurch massacre has spoken out, pleading for peace.

Pleading for the death of his sister Linda Armstrong, nee Gosse, not to be in vain.

Tony Gosse called March 15 the "darkest day" of his life after a lone gunman targeted Masjid Al Noor next to Hagley Park and the smaller mosque in Linwood.

Armstrong was worshipping in the Linwood mosque at the time of the attack and was one of 50 people who were killed in the attacks on the two mosques.

"At 65 years old and with gammy knees she was hardly a threat," Gosse said.

"She always attended Friday prayer time and due to her age and health she always sat in a chair, so was an easy target, with bullets slicing her open in her mid section.

"I pray it was a quick death and hopefully she was the first to die so she didn't have to witness the rest of the terror attack.

"I will never know, I can only hope."

His sister was peaceful with a stubborn ideology of this world, he said.

"We didn't always see eye to eye but she lived a very humble lifestyle and was always unselfishly helping others.

"She volunteered at refugee centres and was an advocate for women's rights.

"She was a mentor for many Islamic women and would mediate between disagreeing parties.

"She always had an open ear and a shoulder to lean on.

"I sincerely hope this massacre and my sister's death does not go unnoticed and not without a lesson to be learned."

Gosse said embracing humility would be what saved the world.

"We are all equal on this Earth and we all have an important role to play with no one person being better or more important than any other," he said.

"We need to remember this and apply it in all aspects of our lives."

He urged others to think about how their words and actions would affect others.

Do unto others as you would have them do unto you was a simple creed, he said.

"Let's all embrace it and live by it," he said.

There would be no wars, no hatred, no racism, no conflicts, no crime, he said.

"We would all be at peace in one big melting pot."

Gosse said he did not want his sister's death to be in vain, and pleaded with people to give peace a chance.
