Whitney Houston 's only child opened up Sunday about her late mother in her first interview since the singer 's death last month . Bobbi Kristina Brown , 19 , told Oprah Winfrey she can still hear her mother 's voice sometimes and feel her spirit , urging her to `` keep moving . '' `` She 's always with me . I can always feel her , '' Brown said during the interview that aired on Winfrey 's network , OWN . On the same show , Winfrey also spoke to Houston 's sister-in-law and friend , Patricia Houston , and her brother , Gary Houston . Whitney Houston , 48 , died February 11 in her room at the Beverly Hilton Hotel in Beverly Hills , California , the day before the music industry gathered for the Grammys in Los Angeles . The famed singer won six Grammys and sold 170 million albums , singles and videos during her career . But in recent years , her struggles with drug addiction overshadowed her accomplishments . When asked whether she feared drugs would one day take her friend , Patricia Houston told Winfrey she `` would be kidding '' to say otherwise . `` The handwriting was kind of on the wall . '' Recently , she said , she observed Houston `` chasing a dream , looking for love in all the wrong places . '' Houston was married to singer Bobby Brown from 1992 until 2007 . Bobbi Kristina was born in 1993 . `` I 'm her daughter . I got ta keep moving . I got ta carry on her legacy . ... I still have a voice , '' Brown told Winfrey . Whitney Houston toxicology reports pending . The grief comes in waves still , Brown said , and sometimes it does n't seem real that her mother is gone . `` I 'm getting through it . I 'm doing as good as I possibly can , '' she said . `` Just trying to keep going . '' Sources close to the investigation into the singer 's death told CNN on Friday that officials were looking to speak with her daughter before closing the case . They said it was unclear whether Bobbi Kristina would agree to be interviewed . She was interviewed briefly by Beverly Hills police the day her mother died , but she was too distraught to offer helpful information , the sources said . She was taken twice to a Los Angeles hospital briefly after her mother 's death , a source close to the family said last month . Investigators have wrapped up the logistical part of their inquiry by having contacted all physicians and pharmacies with ties to Houston , and nothing so far appears criminal , the sources said . Authorities are reviewing additional medical information that will be used in the final ruling on cause of death , and Houston 's toxicology report should be complete `` on or around '' March 23 , the sources said . Last month , officials with the Los Angeles County coroner 's office said the singer 's body had no visible signs of trauma and foul play was n't suspected . Her cause of death was listed as `` deferred , '' officials said . More official details on the investigation have n't been released because the Beverly Hills Police Department was granted a `` security hold '' on the case , the coroner 's office said . Common in high-profile cases , the hold restricts the release of information . Authorities have said that police and fire officials were called to Houston 's hotel room after her unconscious body was found in the bathtub , just hours before she was to attend a pre-Grammy party . A coroner official last month downplayed the suspicion that drugs had played a major role in Houston 's death . Assistant Chief Coroner Ed Winter said that `` not many prescription bottles '' were found in the singer 's hotel room . `` I know there are reports that she maybe was drowned or did she overdose , but we wo n't make a final determination until all the tests are in , '' he said last month .
Houston 's sister-in-law says the late singer was `` chasing a dream '' She and Bobbi Kristina Brown , Houston 's only child , speak to Oprah Winfrey . The woman who claims she is Houston's sister tells Oprah Winfrey that her mother had been having an affair with Bobby Brown, then 18, when he died in 2009. Houston , 48 , died in her Beverly Hills hotel room last month .
