Portland's Sudanese community expressed frustration Monday with what members see as the city's failure to curtail growing violence involving Sudanese victims.

They voiced their concerns in response to Sunday's fatal shooting of James Angelo, 27, the son of one of Maine's most prominent Sudanese leaders.

Angelo, an unarmed security guard at Mercy Hospital, was shot in a hospital parking lot along Winter Street shortly after 4 a.m. as he returned to work after a break. He died later that morning.

An autopsy Monday by the state Medical Examiner's Office concluded that Angelo died from a gunshot wound in the area between his upper back and neck.

Police, who have yet to identify suspects in the shooting, said multiple shots were fired. They have not said whether Angelo was the victim of a random attack.

Witnesses described a possible interaction between Angelo and two people before the shots and reported that two people fled in opposite directions after the shots, according to police.

On Monday, a delegation of 11 members of the Sudanese community met at City Hall with Mayor Ed Suslovic, City Manager Joseph Gray, acting Police Chief Joseph Loughlin and Rachel Talbot Ross, president of the NAACP's Portland branch and the city's director of equal opportunity and multicultural affairs.

In a letter to officials, the Sudanese leaders said they no longer view Portland as a safe city. They said that police have not made arrests in several incidents of violence against Sudanese victims, particularly over the last two years.

The letter listed seven unsolved cases, including a shooting in December of a 20-year-old Sudanese man who was standing outside a Somali community center, and an incident on March 12 in which an unidentified man fired four shots into the home of a Sudanese family on Hammond Street. That shooting prompted the family to leave the city.

"The Sudanese community lives under fear of many things, one of which is the lives of its members, and second, for its inability to control the upbringing of its children," the letter said.

Loughlin said he could not compare the level of crime affecting the Sudanese community with that of other groups in the city because he did not have statistics available. He said police are working hard to solve the cases listed in the letter and plan to make an arrest in one of them.

The letter was delivered on behalf of Angelo Okot, the victim's father and president of the Sudanese Community Association of Maine. Okot described the group as having 2,000 members. He did not attend the meeting at City Hall.

Earlier in the day, Okot said he had thought Portland would be a good place for his refugee family to settle.

"Now somebody jealously came to rob my lovely son from me to kill him without cause," he said.

After a memorial service for his son was held in the parking lot at Mercy Hospital, Okot said he had heard that his son was threatened at work on Aug. 16 in an incident that involved police and a group of young people.

Okot said Angelo reported the incident to his supervisor, but Okot worried that not enough was done to ensure his son's safety. "I believe these kids were looking for him," Okot said.

The hospital did not return a call seeking comment on the Aug. 16 incident. It has referred questions about the shooting to police.

Police said the Aug. 16 incident is just one of many factors in their investigation.

Loughlin said police are still working around the clock on the case but have not received many tips. He repeated a call for the public's help.

Police are looking for two people who were on Winter Street at the time of the shooting. One was described as a short black man in his early 20s with a slight build and short hair. The man appeared to be clean-shaven and was wearing black pants and a white hooded sweatshirt with a design...
