A TRANSSEXUAL killer jailed for 10 years for frightening an elderly woman to death 15 years ago during a bungled robbery has been found guilty of robbing and violently bashing an 82-year-old woman.

A Brisbane District Court jury deliberated almost six hours before finding transsexual Derek “Shanika” Sinden, 45, dressed as a woman, followed the octogenarian home from a suburban shopping centre, bashed her, took her credit cards and used them to go on a shopping spree.

Sinden, who the jury was told identified as a woman, robbed Margaret Baker, 82, after following her home for the Toombul Shopping Centre, on Brisbane’s northside, before rendering her unconscious and robbing her about 1pm on January 12 this year.

What the six man, six woman jury were not told was that Sinden had served almost 10-years in jail for slaying 71-year-old Beryl Grace Brown after attacking her and scaring her to death in her Woolloogabba home, in Brisbane’s inner-south, in April 1999.

During Sinden’s July 2005 Supreme Court trial it was revealed the transsexual terrorised Mrs Brown, causing her to have a heart attack and fatal stroke,

Sinden pushed Mrs Brown face-down on a bed before turning her over, sitting on her chest and pushin a pillow into her face while demanding to know where she kept her money.

Sinden dragged her through the house in a search for money, until the elderly woman scrambled to a window and screamed for help.

Sinden had pleaded not guilty to murdering Mrs Brown, but was later convicted on the lesser charge of manslaughter.

A trial presided of District Court Judge Helen Bowskill was this week told Sinden was dressed like a woman when he robbed Mrs Baker.

The jury was shown closed circuit television footage of Sinden follow Mrs Baker 30-seconds after she left the shopping centre and return 20-minutes later dressed in different clothes and in possession of the elderly woman’s credit cards.

The jury found Sinden had followed Mrs Baker to her nearby unit complex -- a 10-rminute walk from the shopping centre -- and violently rob her.

Sinden on Monday pleaded not guilty to one count each of robbery with violence, stealing and two of fraud.

However, she pleaded guilty to an additional seven counts of fraud.

Sinden lobbied unsuccessfully to be housed in a women’s prison when she was first arrested and earlier applied to the Queensland Civil and Administrative Tribunal alleging she was discriminated against when refused female hormone treatment.

But the claim was dismissed when QCAT member John Oliver found Sinden was not treated any less favourably than any other prisoner.

Judge Bowskill will sentence Sinden at a date to be fixed.
