( CNN ) -- Elizabeth Johnson -- whose 8-month-old baby , Gabriel , disappeared in 2009 after she allegedly took him to Texas -- was found guilty Thursday of unlawful imprisonment and custodial interference . Johnson also was originally charged with kidnapping , but the jury could n't reach a verdict on that charge . Instead , the jury found her guilty with aggravating circumstances on the lesser charge of imprisonment and two custodial interference charges . Her next appearance in court will be November 1 when the judge will set a sentencing date . She has already served nearly three years in jail , having been taken into custody shortly after Gabriel disappeared . He was 8 months old when he was last spotted alive at a Texas motel in late 2009 . What happened to him is unclear . Johnson originally told the boy 's father that she had killed Gabriel , but after she was arrested , she told police that she gave the baby to an anonymous couple in San Antonio , CNN affiliate KPHO-TV reported . Police in San Antonio searched a landfill and found nothing . There also have been searches in Arizona and Florida , according to HLN , the sister network to CNN . The San Antonio police website lists Gabriel as a missing person . The mystery began December 17 , 2009 , after a judge awarded Johnson and Logan McQueary , the boy 's father , joint custody of Gabriel . But Johnson allegedly defied the ruling and set out for Texas with her son . McQueary did n't hear from Johnson until several days later , when she reportedly sent him a text message saying she 'd killed Gabriel and put his body in a Dumpster . `` I killed him , '' Johnson said in a text to McQueary on December 27 , 2009 . `` U will never see Gabriel again , I made sure of that . And you can spend the rest of ur pathetic life wondering about him . '' The scathing series of texts continued . `` U will never find me im already bording a plane . Out of the country , '' Johnson said . `` When im safe ill email u the exact location of dead gabriels little blue body . If the garbage do n't come first . '' McQueary also recorded a phone call from Johnson in which she made similar claims . Johnson : `` You made me do this . '' McQueary : `` You did not hurt Gabriel . '' Johnson : `` Yes , I did . I suffocated him . ... . I suffocated him and he turned blue . And I put him in his diaper bag and I put him in the trash can . '' Johnson was arrested on December 30 , 2009 , in Miami Beach , Florida . She told police she gave Gabriel to a unknown couple under the direction of a woman named Tammi Smith . Johnson and Smith had met in June 2009 , when both women were waiting for the same flight in the Indianapolis airport . Smith suggested to the young mother that she and her husband adopt Gabriel . Johnson said she called Smith that December to ask if the couple was still interested . In May , Smith was found guilty of forgery and conspiracy to interfere with Gabriel 's custody . She was sentenced to probation and 30 days in jail . Smith 's conviction does not relate to the boy 's disappearance , but her efforts to conspire with Johnson to deny McQueary his rights to see his son . Smith told the court that she helped Johnson and helped care for Gabriel for nine days . Smith eventually apologized for any `` pain and suffering '' that helping Johnson may have caused , even as she firmly insisted that her intentions were good .
