Murder probe detectives found web search for serial killers
Police found an internet search for "Scotland serial killers" during an investigation into two women charged with murdering a disabled woman.
Officers also discovered checks for "Peter Tobin" and "Peter Manuel".
There was further research online for how long "the integrity of a crime scene" is kept.
They were found after the body of Sharon Greenop was discovered at her home in Troon, South Ayrshire, in November 2016.
Her sister Lynnette Greenop, 40, and her daughter Shayla Greenop, 20, are accused of her murder. They deny the charges.
It is claimed Sharon Greenop was assaulted on various occasions between 8 September and 10 November 2016.
The High Court in Glasgow heard police examined two Samsung phones during the investigation.
Number of victims
The jury was previously told Shayla Greenop had earlier handed over a mobile voluntarily.
Police Scotland's Cyber Crime Unit carried out checks on phones, including what had been accessed online.
The trial heard there had been an internet search for "Scotland serial killers".
A check of the web history further revealed a number of sites had been looked at.
This included a search on Wikipedia for "Peter Manuel".
Amongst other names were "Peter Tobin", "Robert Black" and "Archibald Hall".
A further check was for a "list of serial killers by number of victims".
Other searches included "How long is the integrity of a crime scene kept" and "How long to complete an adult adoption".
Bloodstains in bedroom
The trial also heard on Monday from a forensic scientist who said that blood spots matching the DNA of Sharon Greenop were found on a wall beside her bed and on a mattress protector.
James Hawkins said he visited the Greenop's home along with a pathologist and police officers while Sharon Greenop's body was still in the bed.
He examined the bedroom for bloodstains.
He told prosecutor Ashlie Edwards that a small piece of body tissue with clotted blood and a single hair on it was also discovered in the bedroom. This also matched her DNA.
Referring to the bloodstains Mr Hawkins told the court: "In my opinion this could be explained by Sharon Greenop having been repeatedly struck whilst bleeding and lying on the bed."
Defence QC Frances McMenamin, representing Lynette Greenop, asked Mr Hawkins: "You can't say when that blood or DNA was deposited," and he replied: "No, that's not possible."
The jury heard that the rest of the house was also examined for bloodstains and none were found.
The murder charge alleges Sharon Greenop was repeatedly struck with object or objects and had her neck compressed.
It is said injuries were also inflicted "by means unknown" and that there was a failure to obtain medical help.
The two accused, who both live in Ayr, deny all charges.
The trial, before Lady Carmichael, continues.
