Biography
In 2010, John helped Andy with security at a party for Tommy Merlyn's birthday at the Merlyn Mansion.

Sometime between 2010 and before Oliver's return to civilization, while working as a bodyguard, Andy was shot and killed by Deadshot with poison-laced bullets, hired by a group named H.I.V.E.. His death was cleverly covered up by Lawton to make it look like he was targeting Andy's client but in reality, Andy was the target.

It was later revealed that Andy's murder was Deadshot's first mission for H.I.V.E. and as a killer for hire. Andy's name was tattooed prominently on Lawton's right pectoral muscle.

Behind the scenes

 * Andy is likely named after Andy Diggle, the author of Green Arrow: Year One, upon which the first season of Arrow is largely based.
 * In the Arrow comic chapter, "Aftermath", Andy is stated to have died on April 8, 2009. However, this was retconned in-show in the Arrow episode,, in which he is still shown to be alive in 2010.
