The Brazilian woman accused of killing three relatives with a poisoned Christmas cake has been found dead in her jail cell.
Deise Moura dos Anjos, 42, was found lifeless in her cell at a women’s prison in Guaiba on the outskirts of the southern city of Porto Alegre this morning.
Police chiefs say they are treating the death as a suicide and sources at a regional emergency response service said she appeared to have hanged herself.
Deise was remanded in prison on January 6 on suspicion of three murders and three attempted murders.
Her mother-in-law Zeli dos Anjos had baked the cake eaten by several relatives late on December 23 and later found to have been contaminated with arsenic-laced flour.
The victims, including Zeli, took several bites and found that it had a ‘spicy’ flavor, as the family gathered for coffee, Police Chief Marcos Veloso told RBS TV at the time.
Zeli, 61, was hospitalised but survived.
Her teacher sister Maida Bernice Flores da Silva, 58, another sibling called Neuza Denize Silva Dos Anjos, 65 and Neuza’s daughter Tatiana Silvia Dos Santos, 43, died within hours of eating the cake.
Tatiana’s 10-year-old son Matheus, Zeli’s great nephew, was also taken into intensive care and spent several days in hospital. Maida’s husband Jefferson needed hospital treatment too.
Deise was protesting her innocence but police branded her an alleged ‘serial killer’ after her arrest.

Police in Torres in southern Brazil where the three poison victims died said at a press conference after her detention the evidence they had against her was ‘robust.’
Forensic experts confirmed after Deise’s arrest early last month the cause of the deaths of victims was arsenic poisoning.
Margaret Mittman, Director of the Rio Grande do Sul General Forensic Institute which covers Torres, said: ‘The source of that arsenic poisoning was the cake eaten by the victims and the source of the contamination of the cake was the flour found in Zeli’s house in Arroio do Sol.’
She revealed tests on the victims’ urine and blood samples as well as the contents of their stomachs had revealed ‘fatal levels’ of arsenic up to 350 times higher than those which would be regarded as ‘naturally-occurring.’
She added: ‘Extremely high levels of arsenic were found in the tests done on the three people who died.
‘They were such high levels they were considered toxic and lethal.’
Police were also probing whether Deise killed her father-in-law Paulo Luis dos Anjos, who died last September after eating bananas mixed with powdered milk she had taken him.

Local police chief Marcus Vinicius Muniz Veloso spoke after her arrest to describe Deise as the only person who had upset the ‘harmonious’ family relationship that existed between the poison victims.
He said: ‘The family relationship was harmonious but there were disagreements caused by only one person and that person was investigated and we were able to build up evidence pointing to her committing three murders and three attempted murders.
‘I can tell you those differences I’m talking about date back 20 years. They were very minor.
‘The family told us about those disagreements.’
Police and prison authorities will now carry out separate investigations into Deise’s jail cell death.
She was alone in the cell where she was found dead.
