LAWRENCEVILLE - Gwinnett County police said a fight over a puppy was behind the stabbing death of a Lawrenceville man early Wednesday morning.<br />
<br />
Investigators said 51-year-old Joseph M. Kollie was stabbed a number of times by his stepson after the two argued over a puppy the stepson had brought in to the home on Congress Parkway.<br />
<br />
Diamond G. Mason, 23, has been charged with felony murder and aggravated assault in the incident.<br />
<br />
Officer said they were called to the residence just before 1:15 a.m. During the course of the investigation, they determined that Kollie and Mason had been fighting over the dog ever since Mason brought the animal into the home about a week ago. The argument escalated late Tuesday night and into the early hours of Wednesday morning, according to officers, when Mason stabbed his stepfather with a couple of large knives.<br />

Mason is being held without bond at the Gwinnett County Jail.<br />
