BAYOU L'OURSE - Investigators are looking for answers as to why a war veteran and his son were murdered inside their Assumption Parish home, before the killer took his own life.

The man who killed the two victim's before taking his own life was a neighbor who lived across the street, according to investigators. Assumption Sheriff Mike Waguespack believes an altercation over property boundaries may have set the man off.

"It's a very tragic situation," Waguespack said. "Not certain what caused this guy to get violent. Very horrific crime scene."

Investigators said Mark Massoletti, 52 and his son, Michael Massoletti, 23, were killed with some kind of sharp objects inside their home on Felecia Street around 4 a.m.

"He entered that home, went straight to the master bedroom and attacked that man," Waguespack said.

Deputies said William Powers Jr. was the killer. He was recently released from jail on misdemeanor battery charges and lived across the street. Reportedly he had words with Mark Massoletti, who previously told him to stay off his property.

"The only thing we know is that the week before, he was warned," Waguespack said. "(The) resident warned the suspect to not cross the line as far as property is concerned, or they would have problems."

Powers killed both men and injured two woman in the melee who escaped and called for help. Waguespack said Massoletti was a Marine veteran who collected guns and weapons that the suspect may have used on the victims before he pulled out a gun, shot and killed himself

"Strong possibility some of the weapons in the house were used to attack him," Waguespack said.

An autopsy will be done Tuesday to determine an exact cause of death for each of the victims.
