The photographer used a special filtering technique to highlight the bloodstains

These chilling crime scenes pictures show the inside of houses where family members have been killed, from an artist's point of view.

They were taken by American photographer Angela Strassheim as part of a series called Evidence, and show how the traces of violence remain long after the crime has taken place.

Many of the images are named after the murder weapons used, such as 12 inch stiletto knife and two Mossberg twelve-gauge shotguns.

The pictures come from 140 locations across the US, using a special solution called Blue Star to reveal traces of blood on the walls despite the cleaning, repainting and subsequent re-habitation of these homes.

Spatters of various sizes are found against walls, skirting boards and shelving throughout otherwise normal, every day households. No other information is given about the crimes or what took place, instead leaving it to the viewer's imagination.

The black and white images are long exposures – from ten minutes to one hour – with small amounts of  night light pouring in from the cracks of windows and doors, showing the blood as a lurid glow.

In her description of the work, Angela said: "Perhaps we have all processed a question in certain love relationships.

"Could we be a victim of violence or perform an act of violence against a loved one out of our immense capacity to feel jealousy, anger, rage, and desperation in a moment of extreme emotion? 

"These photographs allow for the viewer to entertain the idea that this situation could involve anyone of us."
