62-year-old Edward Ates was convicted Friday in the 2006 murder of Paul Duncsak.

NEW JERSEY (WPIX) - It turns out a New Jersey jury did not buy a Florida man's defense that his wide waistline deterred him from killing his former son-in-law.

62-year-old Edward Ates was convicted Friday in the 2006 murder of Paul Duncsak.

Ates' lawyer initially told jurors his client, who weighed a whopping 285 pounds at the time of the killing, wouldn't have the energy to actually shoot Duncsak and escape to Louisiana.

Ates' weight has caused a myriad of health problems including asthma, sleep apnea and other ailments, his lawyer said.

However, prosecutors claim Ates drove from Florida to Duncsak's home in Ramsey, New Jersey, climbed a staircase and shot the 40-year-old.

When the shooting occurred, Duncsak and Ates' daughter were apparently involved in a bitter custody dispute following their divorce.

The jury reached the verdict on its second day of deliberations after a trial that lasted more than a month.
