PORTLAND, Ore. -- DeDe Spicher, identified as a close friend of Terri Moulton-Horman, was called before a grand jury Monday in Multnomah County as part of the ongoing investigation into the disappearance of her step-son Kyron Horman.
Spicher's attorney told NBC Dateline that he would be "surprised" if Terri was not arrested in the case.
Grand jury proceedings are not open to the public or the media. However, Spicer's attorney did confirm that his client was subpoenaed to testify but did not give any testimony under oath Monday. He said she could be called back to testify in the future.
Reliable sources told KGW that Spicher was doing gardening work not far from the Horman family home in Northwest Portland on the day Terri's step-son, 7-year-old Kyron Horman, disappeared from Skyline Elementary. Spicher reportedly left where she was working at 11:15 a.m. on June 4 and returned around 1 p.m.
However Spicher's attorney Chad Stavley said DeDe was gardening on the day Kyron disappeared and never left the area.
"She's getting asked questions, she's getting treated frankly, like she's a suspect, when she's not," he said.
Stavley also told NBC Dateline Monday that Spicher had been, and planned to keep, cooperating with investigators. He said that she had already shared text messages and emails sent to and from Terri with detectives.
"I would be, frankly, surprised if Terri Horman did not eventually face charges in this case," Stavley said. "I'd be surprised if the indictment didn't come down."
The person who owns the house where Spicher lives, who was cooperating with investigators, told police that she called Spicher on her cell phone but she didn't answer, the source told KGW. A person who was working with Spicher, who was also cooperating with investigators, told them of trying to unsuccessfully find Spicher. Both people have told investigators they have no idea where Spicher was during that period of time.
Sources told KGW that police searched Spicher's home last week. Spicher has known Terri and Kaine for about seven years. Stavley said that Spicher even moved into the Horman home for a time after Kyron went missing.
Last week, Kyron's parents, Kaine Horman and Desiree Young issued a public plea for Spicher to cooperate with police, threatening a possible civil suit if she refused.
