A psychologist recently testified about the upbringing of a teenager involved in a school shooting. The teenager had a chaotic and lonely childhood, and was part of an online community interested in mass shootings. The shooting occurred at Apalachee High School in Georgia, resulting in the deaths of two students and two teachers.

Several others were also wounded in the incident. The teenager, Colt Gray, pleaded guilty to 55 counts, including murder. Further details about the case and the sentencing hearing are available from the source.

The sentencing hearing is ongoing, with the judge to decide on the possibility of parole.
