Updated at 8:55 p.m. Thursday: One of two Walter Johnson High School students who were considered missing has returned home, Principal Jennifer Baker announced Thursday night.

In a message to the school community, Baker said, “Today we learned that Jessica Montoya has returned home. This is great news,” Baker wrote in a message to the school community.

Baker noted that the other student, Gladys Rios-Gonzalez, was still missing. “Please share any information that you may have regarding this case,” Baker wrote.

On Tuesday, Montgomery County police had issued separate press releases about Montoya of the 600 block of Kingsford Road in Bethesda, who had last been seen leaving school after dismissal on Monday, and Rios-Gonzalez of the 5900 block of Montrose Road in North Bethesda, who was seen leaving school at the end of classes on March 15.

Neither of the 15-year-olds had returned home or contacted their families about where they were going. At the time, Sgt. Rebecca Innocenti, a department spokesman, said detectives believed the two 15-year-olds have some of the same friends, but they didn’t know if the missing girls are close friends.

“There’s no indication that the cases are related in that there’s no indication that the girls are together,” she said Tuesday.

On Monday, Baker had sent an email about Rios-Gonzalez to the school community asking anyone with information to call school officials or police.

A missing person poster shared by Baker stated Rios-Gonzalez was seen contacting someone by phone Thursday afternoon, after which a woman picked her up in a small gray car in front of the school.

Police describe Rios-Gonzalez as 5 feet 4 inches tall and 150 pounds. She has black hair and dark brown eyes. She was last seen wearing a black jacket over a plaid green-and-black shirt, dark blue pants and black Puma sneakers. She was carrying a red backpack.

Police have asked anyone with information about Rios-Gonzalez to call 301-279-8000.
