The attorney for 42-year-old Dan Popp are trying to convince a Milwaukee County jury that his client shouldn’t be held legally responsible for killing three people. Popp pleaded no contest to charges he shot Phia Vue, Mai Vue and Jesus Manso-Perez to death in an apartment in March 2016. The Hmong community has called for Popp to be charged with hate crimes. Popp has been examined by mental health experts five times, so far. If the insanity defense is rejected, he would receive mandatory life terms for each of the killings. He’s also accused of attempted murder for the shooting of Jesus Manso-Carraquillo.
