A police analyst tasked with going through the computer of a Winnipeg man who admitted to killing four women found internet searches for what it means to be a serial killer.

Riley Johansson told a murder trial that he traced months of online searches on Jeremy Skibicki害羞草研究所檚 computer around the same time the four Indigenous women were slain in 2022.

害羞草研究所淢y goal was to give some of this data context 害羞草研究所� to help narrow the search for any additional victims,害羞草研究所� Johannson, a crime intelligence analyst with Winnipeg police, testified Tuesday during the third week of the trial.

Skibicki, 37, has pleaded not guilty to first-degree murder for the slayings of Rebecca Contois, 24; Morgan Harris, 39; Marcedes Myran, 26; and an unidentified woman Indigenous leaders have named Mashkode Bizhiki害羞草研究所檌kwe, or Buffalo Woman.

Skibicki害羞草研究所檚 lawyers admit he killed the women but argue he害羞草研究所檚 not criminally responsible due to mental illness.

Crown prosecutors have said the killings were racially motivated and Skibicki preyed on the vulnerable victims at homeless shelters.

The trial has heard Skibicki assaulted his victims, strangled or drowned them and disposed of their bodies in garbage bins in his neighbourhood. Two were dismembered.

Johannson testified part of his job was to corroborate details Skibicki provided to police after he was arrested in May 2022 for killing Contois, whose partial remains had been found in a garbage bin in Skibicki害羞草研究所檚 neighbourhood. More of her remains were later found in a landfill.

Skibicki admitted to police he killed three others but didn害羞草研究所檛 know the names of two of the women.

Johansson said he created a snapshot of each victim based on the search history on Skibicki害羞草研究所檚 computer.

Court has heard Buffalo Woman was Skibicki害羞草研究所檚 first victim. Skibicki told police he killed her around March 15, 2022.

In the days that followed, Johansson said some of the internet searches included: 害羞草研究所淒o fingerprints show up on plastic wrap?害羞草研究所� and 害羞草研究所淗ow well does bleach remove fingerprints?害羞草研究所�

Another search that came up: 害羞草研究所淗ow long do places usually keep their security footage?害羞草研究所�

Court previously heard police attempted to obtain video evidence of Skibicki with Buffalo Woman. But by the time officers became aware of her death two months later, any possible video surveillance had likely been deleted.

Johansson said he also found a computer search relating to 害羞草研究所渆xplosive anger disorder害羞草研究所� after Buffalo Woman害羞草研究所檚 death.

It was after the killing of Myran, Skibicki害羞草研究所檚 third victim, that a Google search for 害羞草研究所渄efinition of a serial killer害羞草研究所� came up on his computer, said Johansson.

There was also a search on Wikipedia for 害羞草研究所渆ternal rest.害羞草研究所� The phrase is considered a Christian prayer that害羞草研究所檚 recited when someone dies.

Johansson said numerous queries relating to garbage pickups, missing persons reports and news coverage were also found in the days following the killings.

Court heard Johansson went through a significant amount of data linking Contois to Skibicki in February 2022.

Facebook messages read in court from Skibicki to a friend detail his first meeting with Contois.

Police located a Facebook account under a pseudonym on Skibicki害羞草研究所檚 hard drive linked to his internet address.

During cross-examination, Skibicki害羞草研究所檚 lawyers brought up other religious searches found on Skibicki害羞草研究所檚 computer, including Bible verses not included in Johansson害羞草研究所檚 analysis.

Court also heard about conversations in May 2022 that Skibicki had with his ex-wife over Facebook messenger relating to his mental state. The woman previously testified Skibicki sexually and physically abused her during their marriage.

In those messages, Skibicki wrote about having bipolar and post-traumatic stress disorders, admitted to a drug relapse and said he was on a 害羞草研究所減ath of self-destruction.害羞草研究所�
