No big loss as far as I can tell....
By the time of his first arrest at 15, Carlos De Luna was a 7th-grade dropout who liked to sniff paint and glue.
His rap sheet eventually would include nearly two dozen crimes, mostly offenses such as public drunkenness, disorderly conduct, auto theft and burglary. He was in and out of juvenile detention, but it wasn't until a 1980 arrest that he faced time in an adult prison.
He was then living with relatives in Dallas and working at a Whataburger franchise.
Charged with attempted aggravated rape and driving a stolen vehicle, he pleaded no contest and was sentenced to 2 to 3 years.
Paroled in May 1982, De Luna returned to Corpus Christi. Not long after,
he attended a party for a former cellmate and was accused of attacking the cellmate's 53-year-old mother. She told police that De Luna broke three of her ribs with one punch, removed her underwear, pulled down his pants, then suddenly left.
He was never prosecuted for the attack, but authorities sent him back to prison on a parole violation. Released again in December of that year, he came back to Corpus Christi and got a job as a concrete worker.
Almost immediately, he was arrested for public intoxication. During the arrest, De Luna allegedly laughed about the wounding of a police officer months earlier and said the officer should have been killed.
Two weeks after that arrest, Lopez was murdered.
