WATERVILLE — Waterville police are investigating two separate, unrelated shots-fired incidents that took place Sunday and Monday

Just before 1 p.m. Sunday, police responded to a report of a fight in the parking lot of JFK Plaza on Kennedy Memorial Drive.

“Initial reports indicated a firearm was possibly involved,” Maj. Jason Longley wrote in the news release. “Investigators later learned that there was a firearm involved, and several shots were fired in the vicinity.”

Police believe no one was struck by a bullet during the altercation, Longley said.

“This case remains under active investigation, and no further information will be released until an arrest is made in the case.”

Then, just before 5 a.m. Monday, police went to Brook Street for a report of people yelling at each other.

Subsequent calls indicated that a shooting had occurred at 21 Brook St., apartment 2, the residence of James Furrow, 25, according to police.

“The shooting was a result of an altercation between Furrow and a 31-year-old male, according to police.

Furrow was charged with elevated aggravated assault, a Class A crime, and reckless conduct with a dangerous weapon, a Class C crime.

Brook Street is located off Main Street in the city’s North End.

In both cases, police say, the people involved knew each other.

“We take these cases very seriously and often consult with our federal partners when firearms are involved in the commission of crimes,” Waterville police Chief William Bonney said. “We simply cannot have people endangering the public by discharging firearms in neighborhoods and crowded parking areas.”
