Colin Gray, 55, the father of a teenage boy who shot and killed four people at Apalachee High School in Georgia, has been sentenced to 15 years in prison for murder, manslaughter, and other charges. The sentence was handed down by Judge Nicholas Primm on Thursday, with charges against the defendant being served concurrently. Prosecutors had asked for the maximum punishment of 80 years, but the judge acknowledged that Colin Gray "didn't seek to harm anyone" himself. Investigators said that the rifle used in the shooting was a gift from his father to his son, Colt Gray, who pleaded guilty to the murders last week.

Story summary
Here is a summary of the news story:
Colin Gray, a father in Georgia, was sentenced to 15 years in prison after his son, Colt Gray, carried out a deadly school shooting at Apalachee High School near Atlanta in 2024. The younger Gray killed two students and two teachers before being sentenced to life in prison without parole earlier this week. Prosecutors alleged that Colin Gray gave his son the rifle used in the shooting as a Christmas gift, wrapped in poster board, with the barrel sticking out. Judge Nicholas Primm stated that Colin Gray "failed as a parent" and acknowledged the immeasurable heartache caused by the incident. This is the third time a US parent has been held criminally responsible for a mass shooting carried out by their child.

Why this leaning score
The use of phrases such as 'the one person who could have prevented' and 'failed to do the simplest things to prevent this' implies that Colin Gray's culpability is significant, but the text also attempts to distinguish between his actions and his son's decision-making, suggesting a nuanced view. The tone is critical towards Colin Gray, but not overtly partisan or emotive.
