Bloodstain pattern analysis

Bloodstain pattern analysis (BPA), one of several specialties in the field of forensic science, involves the study and analysis of bloodstains at a known or suspected violent crime scene with the goal of to helping investigators draw conclusions about the nature, timing and other details of the crime.

The use of bloodstains as evidence is not new; however, the application of modern science has brought it to a higher level since the 1970s and '80s. New technologies, especially advances in DNA analysis, are available for detectives and criminologists to use in solving crimes and apprehending offenders.

The science of bloodstain pattern analysis applies scientific knowledge from other fields to solve practical problems. Bloodstain pattern analysis draws on the scientific disciplines of biology, chemistry, mathematics and physics. If an analyst follows a scientific process, this applied science can produce strong, solid evidence, making it an effective tool for investigators, although care does need to be taken when relying on bloodstain pattern analysis in criminal cases. A report released by The National Academy of Sciences calls for more standardization within the field. The report highlights the ability of blood spatter analysts to overstate their qualifications and the reliability of their methods in the court room.

Stains (Los Angeles band)

The Stains is a hardcore punk band from the Boyle Heights neighborhood of Los Angeles, California. One of the first East Los Angeles punk groups, the band started playing punk in 1976. Their debut album, produced by SST Records house producer Spot, was recorded in 1981, and released by SST in 1983. The band has been on tours with Black Flag, Hüsker Dü and countless others. They were one of the bands that played at a 2001 "anniversary show" memorializing the landmark East Los Angeles punk venue Vex Populi (and music writer Josh Kun wrote in Los Angeles magazine that their set was "punk rock enough for the Stains to leave a pool of blood on the stage's wood beams").

On the album, the band's members were Robert Becerra, guitar; Ceasar Viscarra, bass; Gilbert Berumen, drums; and Rudy Navarro, vocalist. Their style is described as hardcore and speedy, and as an innovator in bringing elements of metal into hardcore. Guitarist Robert Becerra's performance style was a model for Greg Ginn's musical concepts for Black Flag. Viscarra and another Stains drummer, Louie Dufau, later played with Dez Cadena in his post-Black Flag band DC3, and Viscarra also played with cowpunk band Blood on the Saddle.
