The girl’s autopsy was completed Friday. The cause of death remains under investigation.

Patricia Murphy, of Winthrop, has made the walk to the area many times but this time it was with a heavy heart.

“I grow roses in my yard and I have three beautiful roses,” she said, “And I just brought them down.”

“I don’t know how somebody can just (leave) a little baby (there) like trash…the poor little thing,” Murphy added. “…It’s heartbreaking.”

Many of the walkers on Saturday stopped at the rocky beach where the girl’s body was discovered near the edge of the water in a plastic bag.

“(It’s) very sad to think (about) something like this, especially when I have a granddaughter who is two years old,” said Winthrop resident Martin Vasquez. “They’re so beautiful. It’s a shame.”

Winthrop resident Ann Vasquez says “someone’s got to miss her.”

Everett resident Ken Jarvinen said it’s unfortunate to hear news like this.
