They are being charged with first-degree murder, attempted first-degree murder, aggravated criminal damage to property and simple criminal damage to property. A juvenile girl was also arrested, police noted.The arrests came as a result of a multi-agency investigation into the "Shiesty Gang Kartel" accused of auto thefts, burglaries and other crimes in Livingston, East Baton Rouge and Ascension parishes. Matthews and Hardesty were arrested in Livingston Parish and are being held in the Livingston Parish Prison. Hackett is in the East Baton Rouge Parish Prison; the juvenile is in the East Baton Rouge Juvenile Detention Center.Multiple other alleged gang members were arrested. Khristian McManus, 17, Deonta White, 24, and Chance Hebrand, 23, were also arrested, Baton Rouge Police said.

While no arrest can ever replace the presence of a loved one, we hope this development brings some measure of peace to the community, and to those who knew and cared for him," East Baton Rouge Parish Mayor-President Sid Edwards said in a statement. "Baton Rouge will not tolerate senseless violence."Harrison's aunt Mary Utz said he was doing some plumbing work for a friend's father. The father had dementia and had been given a high estimate on some work that needed to be done. Utz said that Harrison knew he could do the job for much less.Harrison was getting out of the plumbing business and was less than a month away from receiving a degree from Southeastern University when the fatal shooting happened, Utz said.Permalink| Comments ...read more read less
