onday, Police Chief Shon Barnes said investigators weren't sure if the second shooter was among the dead. Neither he nor the mayor made any reference to additional shooters. Barnes had been out of town Sunday, attending a conference of Black law enforcement executives in Dallas.

The officials defended their handling of the case, saying they were trying to ensure they provided accurate information about chaotic events.

The victims included a father of three

The King County Medical Examiner's Office on Monday identified the dead as Carlos Israel Sanchez Villalba, 44; Ashley Whitehead, 56; and Junior Cee Niko Semo, 19.

Villalba was a husband and father of three known for his kindness and willingness to help others, according to a GoFundMe campaign launched Monday to help his family with funeral expenses. He died from a gunshot wound to his torso, while Whitehead died from a gunshot to her pelvis and Semo died from multiple gunshot wounds, according to the medical examiner's office.

Whitehead had just moved to Washington from Alabama a year ago and was enjoying the festival with one of her adult daughters when she was shot, her cousin Michelle Whitehead told The Associated Press. She was taken to the hospital and died in surgery, she said.

Ashley Whitehead adored her two adult daughters, and also loved nature and arts and crafts, her cousin said.

 I would consider her just a free spirit. She had the best sense of humor, the best gorgeous smile,  she said.

During a vigil Monday night at the center, Michelle Whitehead stood among dozens of others with a sign that said  Whitehead Strong  as the group held a moment of silence and raised up flashlights on their phones to honor those that had been killed. Candles and flowers were arranged around them.

The four wounded included a 2-year-old boy, two men, ages 23 and 27, and a woman, 39, all of whom were discharged, a hospital spokesperson said.

One of the victims was walking a bicycle when struck, the court document said. The toddler was with his mother.

Vendors returned to venue to clean up

Vendors were allowed to return to the campus Monday morning to collect their equipment. Skewered squid on grills, roasted ducks in ovens and plates full of food were among the items left behind as people fled.

Near the spot of the shooting, a stain of what appeared to be blood was still visible.

Dozens of officers were providing security at the event and responded in seconds, with at least one observing a suspect firing, authorities said. Police searched an IMAX theater on the grounds where they initially believed a second shooter had fled.

Adam Lombardo, who had a Burmese food stand at the festival, described the panic of fleeing people as a  stampede.  As he gathered his equipment Monday, he described how police escorted food vendors back to the crime scene to turn off their ovens and stoves.

 They just came to enjoy a food festival with people, with friends, with new friends, and they lost their lives in just what sounds like meaningless bloodshed,  he said.

A nearby resident offered shelter to people fleeing

Moises Perez, 30, was cooking in his apartment next to the Seattle Center when he spotted people running and yelling outside his window. When he opened his door, he heard gunshots and started ushering more than a dozen people, mostly women and children, inside.

 I was like,  OK, we need to help these people,'  said Perez, a construction worker who had attended the food festival that morning. He said losing his brother to gun violence in Mexico years ago made him determined to help the people trying to get to safety.

He and his roommate, William Large, 25, made sure the door was locked and started directing people to the bathroom and hallway, and told them they could stay as long as they needed.

 They were definitely in shock. I know that a lot of people were crying, people were screaming, people were just in complete fear,  said Large, who works in social services.

About 30 minutes later, Perez walked out to see what had happened. He found a woman shot in the leg being helped by emergency officials.

The festival started in 1982 and draws 350,000 attendees, according to its website.
