A man accused of killing his so-called "neo-Nazi terrorist" roommates back in 2017 pleaded guilty Monday morning in a Tampa courtroom. Devon Arthurs spent years in a mental health facility after he was deemed not competent to stand trial. Now, he has agreed to spend 45 years in prison and be eligible for parole after 25 years, followed by 15 years of probation. Arthurs was 18 years old when police said he shot and killed 22-year-old Jeremy Himmelman and 18-year-old Andrew Oneschuk. According to police, Arthurs said he had converted to Islam, which didn't sit well with his neo-Nazi roommates.
