David Renner was identified as the murdered airport employee and his brother, Joshua Renner, told DailyMail.com that David’s childhood was “complicated at times because he lived in two separate households, just like any other divorced child.”

“As far as I know, this isn’t the first time David has tried something like this,” Joshua said. ‘There were other times. This time I thought it was different.

The Bexar County Medical Examination Bureau on Monday ruled his death a suicide and confirmed David Renner’s identity.

His brother said in recent months that David had given no hint of self-harm.

“The reason I say that is because he was clean for almost five months and lived every day to the fullest,” he said, claiming “there was no indication this time.”

David had been clean for over eight months, was in therapy, [was] actively taking his prescription medication and had finally become the David we all knew he could be.”

Joshua told how his older brother “loved magic.”

“He always tried to perform a little hand for his friends and family,” he shared.

He also loved making people laugh. He made it his mission to tell everyone at least one joke a day.”

Their parents “made sure he took care of himself” prior to his death on Friday night.

Joshua said his family is now “doing the best they can do right now,” noting that “some days are harder than others.”

“David is one of many others who suffer from mental illness and it’s not always very clear for us to see,” he said.

He urges people to reach out if they sense someone is struggling “because someone random could save the life of a random stranger.”

“The simplest smile can always make all the difference.”
