A Texas man was fatally shot by a neighbor who had come over to argue about a noise complaint, police said.

Edward Trejo, 29, was at a residence on the 300 block of Cincinnati Avenue in San Antonio when he was struck multiple times during the heated altercation just after 5.15am on December 21. 

Trejo was at a holiday party with friends when a neighbor, identified by police as Paul Flores, 40, filed a noise complaint and went next door to complain to the partiers directly. 

Flores confronted Trejo and other tenants in the house, and a verbal argument between the two men broke out. 

The argument escalated into a physical fight and spilled into the front yard and onto the street. As the two fought, Flores pulled out a gun and shot Trejo multiple times. 

Officers who responded to a call about the shooting found Trejo with gunshot wounds throughout his body. They attempted life-saving measures on the scene before the victim was transported to a nearby hospital, where he was later pronounced dead. 

The Bexar County Medical Examiner's Office determined that a gunshot wound to Trejo's neck had been the cause of death. 

Flores was charged with murder and aggravated assault with a deadly weapon the same day, and he was booked into the Bexar Adult Detention Center, where he remains as of Monday, according to county jail records.

If convicted of murder, Flores could spend a maximum sentence of life in prison without the possibility of parole.

Trejo was a well-respected member of his community and a beloved employee at Benson Auto Group in San Antonio. 

Co-workers said the three words that defined Trejo were 'I got you,' and that he was dependable and supportive. A sign with those words now sits on the empty desk at his workplace.

Tributes to the deceased young man, who was affectionately nicknamed 'Fatso' by those close to him, poured in on social media in the days after he was killed. 

Diablos OutSports, an LGBTQ+ community sports league of which Trejo was a member, made a post that said: 'A proud San Antonian, teammate and friend, Edward was known for his kindness, warmth and the way he made everyone feel valued. 

'He dedicated his life to helping others and left a lasting impact on all who knew him. You will always be part of the Diablos family. Rest in peace, Edward.'

On Facebook, Trejo's sister, Ayanna Trejo, made a post addressed to her late brother that said: 'I’m lost for words because nothing I say could ever explain this pain...
