FT. LAUDERDALE (CBSMiami) – One of the three teens involved in the fiery attack on Michael Brewer in 2009 has had some of his sentence reduced.

In a mitigation hearing Wednesday, a judge ruled that prison sentence of eight years will stand for Denver Jarvis but his probation period would be reduced from 22 years to 10 years. The reduction was granted because Jarvis testified against the attack’s ringleader, Matthew Bent, during his trial.

After the hearing Brewer’s mother and grandmother said they were okay with the probation reduction because they are “not out for blood.”

Jarvis, along with Jesus Mendez, both pleaded no contest in the attack. Mendez was sentenced to 11 years. Mendez also testified against Matthew Bent, 18, who was sentenced to 11 years in prison. Bent was not convicted of the most serious charge of attempted murder.

Trial testimony showed the attack stemmed from a dispute between Bent, then 15, and Brewer over a marijuana pipe.
