While no arrests have yet been made, Portland Police announced on Tuesday that the investigation into last week’s fatal shooting near Morrill’s Corner on Forest Avenue is ongoing.

At around 8:45 p.m. on July 30, police responded to the area of 1155 Forest Avenue for reports of a shooting.

Four people were hospitalized as a result of the shooting, three males and one female.

The woman, 54-year-old Susan McHugh of Gray, died from a gunshot wound. Her death was ruled a homicide by the Office of Chief Medical Examiner.

The three male victims were identified by police on Tuesday as a 45-year-old from New Hampshire, a 48-year-old from Yarmouth, who have both been released from the hospital, and a 51-year-old adult male from Gray who remains hospitalized.

Portland Police said on Tuesday that while no arrest in the case has been made, the investigation remains “very active” and a team of over a dozen investigators have executed multiple search warrants related to the shooting.

“We are working with local, State and Federal agencies to identify and build solid evidence to support both an arrest and conviction of those responsible for the murder of Susan McHugh,” Portland Police Chief Dubois said.

“We have released very little information and realize the anxiety that this has caused the public,” Dubois continued. “The decision to withhold the release of information is not taken lightly. We release information after consultation with the investigating detectives and prosecutors with the Attorney General’s Office.”

“The decision is made after weighing several factors and is a collaboration between everyone involved,” he added.
