Alfred Guy Vuozzo's first-degree murder case for the deaths of a father and his adult son near Montague, P.E.I. was adjourned Thursday morning until Oct. 9.

Vuozzo, 46, has been charged with two counts of first-degree murder for the fatal shootings of 68-year-old Brent McGuigan and his son Brendon, 39, last Wednesday on St. Mary's Road, about 10 km from the eastern P.E.I. town of Montague.

On Thursday, Vuozzo's lawyer appeared on his behalf in a provincial courtroom in Georgetown and asked for more time to sift through the evidence.

RCMP say they are also still in the process of transcribing interviews related to the case.

"Everybody wants this dealt with as soon as possible, but at the same time, we want to make sure the matter's fully investigated. There's been a great number of statements taken and they all have to be transcribed," said Sgt. Kevin Baillie.

Before court started Thursday, dozens of family and friends of the victims, and of the accused, gathered outside along with several police officers.

RCMP say they will have an increased police presence at court throughout the proceedings as a precaution.

Baillie says emotions and tensions are understandably high right now, and police want to ensure the situation stays under control.

"The funerals are this week, emotions are still running very high, and we just want to ensure everyone's safety," said Baillie.

Although police said the victims and the accused likely did not have any relationship, there is a historical connection between the two families. Members of their families were involved in a fatal traffic crash more than 40 years ago.

The elder McGuigan's father was the driver of a vehicle involved in a collision in 1970 in which Vuozzo's sister was killed. This has led some Islanders to speculate on a possible connection between the incidents. However, RCMP have not confirmed a link.

Vuozzo, of Lower Montague, remains in custody.
