As a parent, this breaks my heart.
CNN) -- The grandmother of 2-year-old Riley Ann Sawyers said she was devastated to learn she is probably the little girl now known as "Baby Grace."
Police believe 2-year-old Riley Ann Sawyers is "Baby Grace."
1 of 3 Police said Monday that they are "fairly confident" that Riley was the toddler whose body washed ashore in Texas last month.
Sheryl Sawyers said that it's "hard to think that I'll never see her again."
Sawyers broke down in tears repeatedly during the news conference in Ohio and clutched an Elmo doll she had planned to give Riley for Christmas.
Attorney Laura Depledge said the family was focused on bringing Riley back to Ohio for memorial services.
Depledge said the family also wants justice for the girl.
Riley's mother and a man identified as her boyfriend were arrested Saturday.
Kimberly Dawn Trenor, 19, and Royce Clyde Zeigler II, 24, are accused of injuring a child and tampering with physical evidence, the sheriff's department said.
The couple lives in Spring, Texas, a Houston suburb about 75 miles north of Galveston, Texas. Previously, Riley and her mother had lived in Mentor, Ohio.
They reportedly told relatives that Riley was taken by social workers from Ohio in July.
Sawyers said it didn't make sense that authorities would remove the girl without an investigation.
"None of it made any sense," she said.
The family said they had not seen Riley since March.
As they await formal confirmation by DNA analysis, investigators now are focusing on what happened to "our girl," said Maj. Ray Tuttoilmondo of the Galveston County Sheriff's Department. Watch how tips led to a name »
He asked anyone who knew the child or her family to help detectives reconstruct the events of Riley's short life.
The toddler's body, curled in a plastic storage container, was found October 29 by a fisherman. It had washed ashore on an island in Galveston Bay.
"That says it all: a little-bitty shoe," said Tuttoilmondo, holding up a child's pink and white sneaker at a news conference Monday.
Three weeks earlier, the investigator had held up the same shoe, asking he public for help identifying a child police dubbed "Baby Grace." Now she has a name: Riley Ann.
"She has a family. She has people who care for her," Tuttoilmondo said. "Be assured that a box in West Galveston Bay is not where she ended her life."
Investigators circulated composite sketches of a little girl wearing a pink skirt and matching top -- clothing authorities said she was wearing when she was found. The other sketch, a close-up rendering of the child's face, shows a fair-skinned toddler with long blond hair.
Tuttoilmondo said tips poured in from "around the world." Many of the callers said they knew a child who resembled the composite.
Investigators were able to track down more than 80 children referred to by the tipsters. But the whereabouts of another 22 toddlers is still unknown, he said.
"We still need the public's help because we still have 22 little girls with question marks by their names," Tuttoilmondo said.
The case has touched even jaded police officers, Tuttoilmondo said.
"Any way you look at it, we carry a piece of her with us, and we'll always carry a little piece of her with us," he said Monday
