Testimony continued on Tuesday in the Douglas Garland triple murder trial as the court heard from Lindsay Pengelly, who works at Princess Auto in northeast Calgary.

Surveillance video from the store was entered into evidence that showed Garland going to the store, and records showed he bought metal meat saw blades and a large meat hook.

Then Leanne Mein who works at CTR Refrigeration and Food Storage took the stand to identify several types of butcher knives.

Garland has been charged with three counts of first-degree murder in connection with the deaths of Alvin and Kathy Liknes and their grandson Nathan O’Brien.

Beginning on Tuesday morning, Cst. Doug Kraan returned to the stand to speak about the Internet browsing history details stored on the hard drive.

Kraan told the court that one of the more notable items was a Google map search done on the Liknes' home address. The search was done on June 11, 2014 and accessed again on the 17th.

He also said that he found a Kijiji link to a couch for sale by the Liknes and to an eBay listing for a post-mortem surgical autopsy set.

Kraan said that a number of other searches were discovered in April 2014, including links to pages referencing medical instruments used for orthopedic surgery, gynaecology and neurosurgery.

He also found searches for lock picking, with more specific searches on how to pick Schlage locks, the same kind of lock installed on the side door of the Liknes' home.

Under cross-examination, Kraan agreed that since the computer wasn't password protected, anyone could have used it.

On June 24, 2014, Kraan told the court that a search on 'how to drill out a Schlage lock' was made.

A number of other Google searches were also made in regards to the 'force needed for concussion', 'how much force does it take to cause a concussion' and 'best butcher knives', Kraan said.

During Kraan's testimony, Garland was seen in court looking at the report in the monitor and making notes.

He also told the court about Facebook and LinkedIn searches made on both Alvin and Kathy Liknes, as well as a Google map search of Evansburg, Alberta, the city where the pair had planned to move once they'd sold their Calgary home.

On Monday, the court heard from a number of experts who analyzed a hard drive that was found hidden in an open section of ceiling inside the Garland property.

Kraan said that the hard drive had a capacity of about 200 gigabytes and contained a number of directories containing information about weaponry, lock picking, fingerprinting and adult diapers.

He also said there were also folders called 'patents', 'Liknes' and 'gore' on the hard drive and that there were also two documents on DNA removal.

The Crown, at the beginning of the trial, told the court that Garland deliberately and meticulously planned the murders of Alvin and Kathy Liknes.
