AMW Host John Walsh takes you on location to a community outside of Los Angeles; the site of the violent attack which police say was committed by Jesus "Chuy" Canales.
AMW's Avery Mann spoke with John right outside of the home where the crime took place, and just moments before John spoke to the young witness, Marina.
Cops say that Canales, a martial artist who was obsessed with the movie "Blade," impaled his girlfriend with a sword, leaving 9-year-old Marina and her three baby brothers without a mother.
Nothing we can do can bring her back, but bringing Canales to justice could at least help to bring about some closure in these kids' lives and start the healing process.
Evil wins when good does nothing, and we are relying on you to help track down and put this suspected killer where cops say he belongs: behind bars.
