Texas boy, 6, dies months after neighbor allegedly attacked him with a baseball bat

Jeremy Diaz, a 6-year-old boy in Texas who was allegedly hit by his neighbor with a baseball bat in September, died Tuesday after spending two months fighting for his life on a hospital ventilator, according to authorities and his father.

“Early this morning I was checking him and noticed a pale face and eyes with no motion. Then his heart stopped,” Jeremy's father, Arturo Diaz, wrote on a GoFundMe page on Tuesday. “They tried to resuscitate him, but it was not successful.”

Jeremy was sleeping in his bed on Sept. 11 when Daniel Logan, 39, entered the Georgetown home and assaulted him and another person in the house, the Williamson County Sheriff's Office said. Jeremy's skull was fractured in multiple places, causing swelling to his brain, according to an arrest affidavit about the incident.

Daniel Logan's mother was also injured. She followed her son into the neighbor's home after she watched him enter through the shattered back door while holding a bat, and found Jeremy slumped on the floor of his bedroom, according to the affidavit.

After pleading with her son to stop, she was hit in the face with a baseball bat. She suffered a facial laceration and one of her lower teeth were knocked out, according to the affidavit.

Police were called to the home just after 5 a.m. by the suspect's wife, the affidavit said. Jeremy Diaz and the suspect's mother were transported to the hospital for treatment.

Logan was charged with causing serious bodily injury to a child and aggravated assault of a family member with a weapon, according to jail records. The court has ordered a mental health assessment and is holding him on $650,000 bond

Jeremy was doing much better Saturday, Arturo Diaz wrote on the online fundraiser. The family intended to extubate him because he didn’t need a ventilator anymore. His condition worsened rapidly Monday night when he had a neural storm — a stress reaction caused by brain injuries.

"It was the worst storm we had seen and it came out of no where. It was almost 6 hours of hell on earth — I can only imagine the torture he went through," Diaz wrote.

On the night of the incident, Diaz and his wife were awoken by loud banging from the ground floor of their residence, the arrest affidavit said.

Diaz said in an interview Thursday that while he tried to protect his family, Logan swung the bat at him several times but missed.

"I didn't want to chase him because I knew somebody was hurt," Diaz said between tears. "I went upstairs and I saw my boy in a pool of his own blood."

The Diaz family lived next door to Logan for for a year and a half. The weekend before the attack, Diaz said Jeremy waved good morning to Logan and his wife from the patio of their home in the city about 30 miles north of Austin.

"We didn't know that he was going to cross over the following weekend and attack us for no reason at all," Diaz said. "He was just filled with hate."

Diaz said he later noticed Logan made a hole in their wooden fence to cut a grapevine that Jeremy had planted in the garden several days before the attack.

The sheriff’s office said they are awaiting autopsy results from the Travis County Medical Examiner’s Office and if the findings warrant it, will “present the case to a grand jury for the charges to be enhanced to Capital Murder.”

Marc Chavez, the attorney representing Logan, said his prayers go out to the Diaz family, and that he hopes they find peace in this tragic time.

“While the allegations sound troubling, we ask everyone to reserve judgment until all the facts come to light especially while we investigate issues related to serious mental illness,” Chavez said.

Diaz said it was hard to guide Jeremy through his stay in hospital because he couldn't give him answers for why someone might have hurt him.

During his time in the hospital, Jeremy needed a spinal tap, suffered infections and throat swelling, and needed to wear a temperature-regulating suit. His father wrote on the fundraiser that Jeremy wanted to be Iron Man for Halloween, and was “fighting for his life just like a superhero.”

“I was there when he took his first breath and saw him take his last,” Diaz wrote in an update Tuesday. “No parent should see their children buried before them.”

The Diaz family is planning a memorial service for Jeremy at a local church.

Jeremy loved Jiu Jitsu, soccer, and playing the piano, Diaz said in the interview. He was also a role model for his 3-year-old brother, who was also in the house when the incident happened.

Diaz said his son should be remembered for his immense kindness. Once, his father recalled, Jeremy gave away his Transformers toy to another boy at school.

“He had such a beautiful look on his face because he had given one of his favorite toys to a friend who asked for it,” Diaz said.
