Blake Shearer's father, Nate Adams, said Friday morning that doctors are performing a second round of tests for brain function in the 16-year-old boy, who has been in a coma since he was allegedly beaten on Monday over a loud music complaint.

No activity was detected in tests Thursday, Adams said.

"It's not very promising at all that they will be able to save him," the father said.

ORIGINAL STORY (Aug. 9, 2018, 11:30 a.m.)

The 24-year-old man who allegedly beat a Bainbridge teen into unconsciousness on Monday over loud music in a public park is in custody on an unrelated charge.

He was picked up on a parole violation unrelated to the altercation, Elizabethtown police Chief Ed Cunningham Jr. confirmed Thursday morning. He is currently in the state prison in Camp Hill.

He is not currently being identified by authorities.

“There have been no charges filed in this case as of yet,” Cunningham said.

Borough police are working with the Lancaster County district attorney’s office on the investigation, he said.

In a coma

Blake Shearer, 16, has been in a coma at Hershey Medical Center since the fight, according to his father, Nate Adams of Mount Joy.

The boy has not been identified by authorities. But Adams has been open about his son’s condition, asking for the community’s support as Blake struggles for life.

Blake, who lives with his mother and stepfather in Bainbridge, is supposed to begin 11th grade this fall at Elizabethtown Area High School

Dozens of people attended a candlelight vigil for Blake at Elizabethtown Borough Park on Tuesday.

Elizabethtown resident Stacie Carole Wagner said another vigil will be held for Blake at the park amphitheater at 8:30 p.m. Friday.

Complained of loud music

According to a statement from the district attorney’s office, the 24-year-old man approached Blake at Elizabethtown Borough Park at about 5 p.m. Monday and complained of loud music.

There was a physical altercation between the two, although it’s not clear how the fight began.

Adams said his son suffered a serious head injury and has been “unresponsive” since the incident. His brain is swollen and he sustained contusions on his lungs and his heart is enlarged, Adams said.

He said on Tuesday that Blake is not responding to light, sound or touch. A machine is helping him breathe, Adams said.

The man, who apparently fled the park when another teenager approached and took a photo of him, had a 6-year-old child with him during the incident, according to reports.

False identification

Also on Thursday, Cunningham issued a warning not to heed a name and photograph being circulated that claims to identify the assailant in the case.

“The person identified in that post IS NOT the suspect, and he had NO involvement in this incident at all,” Cunningham said in an email.

The case remains a “VERY active investigation,” he wrote.

Cunningham again asked that anyone who witnessed the incident call police at 717-367-6540.

“No piece of information is insignificant, and every witness will be important to our case,” he said.
