Authorities say a car was found crashed in the bushes near the home. The car was traced back to the father's house, where police found a bullet hole in the window and the victim dead inside.
Brendon Matos was found hiding in the bushes near where the car was found.
Police, who have not released a motive, were said to be looking for a handgun or rifle. They were also looking into Brendon Matos' actions over the last 48 hours.
Neighbors tell Eyewitness News reporter Phil Lipof that the suspect did not have mental issues and was a normal kid. They said Nelson Matos was divorced, and his ex-wife lived in Florida.
In the 2004 Randolph High School yearbook, Nelson Matos purchased a yearbook ad that included a picture of his Brendon as a young boy. The ad, taken out the year Brendon graduated, said, "Congratulations. You have always been the center of my life and as you grew, I was very proud of your accomplishments. Cherish your high school memories. Your journey continues; keep up the momentum and continue to make the wisest choices because success will chase you."
