Mata's sister, Nereyda Gonzalez Mata, told KTRK-TV that the young men had known each other since elementary school.
Mata and Paredes-Martinez were together Easter Sunday night at a bar and a house party. Mata reportedly told his girlfriend that next morning he was heading home, but the shooting happened first.
Detectives say Paredes-Martinez could not remember shooting Mata. He reportedly pointed a gun at a Harris County Sheriff's Deputy, but could not fire it.
The victim's sister says Paredes-Martinez shot Mata twice.

Paredes-Martinez went free April 11 after posting $250,000 bond, but the bond was doubled the next day, after a federal judge ruled the amount “insufficient.”
Paredes-Martinez now is held by federal Immigration and Customs Enforcement officers, as he reportedly has admitted he is a citizen of Mexico.
A GoFundMe account set up by Mata's sister had nearly $12,000 in pledges Thursday morning.
“His death came as a total shock to all of us who love him,” Gonzalez Mata wrote on the GoFundMe page.
