⚠ CAUTION: Information presented on this page is blunt and technical, as it's intended for the BC Coroners Service to aid with the recovery of Lisa's remains.  This is the shortest possible version of the facts. There's a lot more to this story, but this is a summary of the details required to actually locate and excavate the grave.


Victim

  • 21-year-old woman of mixed European and Indigenous heritage
  • 52kg, 163cm
  • long brown hair
  • dressed all in black:
    • black shirt
    • black skirt
    • black imitation-leather crop jacket
    • distinctive black thigh-high zip-up thigh-high boots
    • a belt made up of several heavy 4" stainless-steel rings (~8 gauge × ~4″)

Location

Burial Method

  • A deep (possibly 10 feet) hole was dug using a backhoe.
    • The backhoe arrived on a trailer towed by a pickup truck.
  • The body was tossed in, fully clothed, and the hole was immediately back-filled.
    • Witness claims were later corroborated by neighbour who witnessed burial.[1]
      The victim may have still been breathing at the time that she was buried.

Concealment

The grave was intentionally concealed by means of at least two methods:

Concrete

  • Immediately after burial, a 4ft² concrete slab was poured above.
    • This witness claim is corroborated by historical aerial imagery showing the addition of the slab between 1999 and 2003.[2]

Garden

  • Several months later, the concrete square was covered with soil, and a garden was planted above.
    • This witness claim is corroborated by historical aerial imagery showing the addition of a garden sometime prior to 2006.[2]

Unearthed

  • Several years later, new owners unearthed the oddly-located and impractically-sized "patio", which has since been home to a wooden picnic table.
    • This was deduced based on public records and historical aerial imagery between 2009 and 2018.[2]
  • In 2022, a full-sized patio was poured behind the home, incorporating the existing concrete square, which is clearly a different shade compared to the newly-poured area.
    • This claim is based on current satellite imagery.[2]

Recovery

A number of details should be considered prior to excavation of Lisa's remains:

Detection

  • Detection of the remains using Ground Penetrating Radar or a Resistivity method requires removal of the concrete.
  • The coordinates provided are precise however the exact depth is unknown.
    It may be helpful to use a Metal Detector to determine burial depth — the victim was likely buried wearing a belt made up of heavy steel (~4″) rings, and her boots had long ("thigh high") metal zippers.

Equipment

Equipment required for recovery of the remains includes:

  • Concrete saw
  • Jackhammer
  • Mini excavator (eg., 3-ton, rubber tracks)
  • Metal detector (to determine depth)

Additional property details

Bedrock Conditions

Often exposed, area bedrock comprises conglomerate and gritstone, minor sandstone, siltstone and carbonaceous shale and coal.[3] This is due to the presence of the Chase River Fault.

Soil Conditions

The area has high clay content[3] and soil in the area is made up of glacial till generally overlying bedrock.[3]

Climate

Average monthly precipitation varies from 24mm in July, to 193mm in December. 77% of annual rainfall occurs during the 6 months of October to March.[4]

On average, Nanaimo has 180 frost free days per year (50%) mid April to late October.[4]

Chase River Fault

The Chase River Fault, a strike-slip tectonic fault line bisects Colliery Dam Park, forming a geological boundary, and appears to continue directly below the burial location.[3][5]
