"A young lady came out she was running outside and she was screaming just screaming hysterical about what happened," said Yasmyn Horvath, a neighbor.
Officers checked Latus' wallet while investigating and found he was robbed of $160 in cash.
A family member told police that Latus had received a package not addressed to him, and Fleener had allegedly come to the house earlier looking for that package.
Home security footage shows Fleener and Johansen returning to the house later and more security video on a Milwaukee County bus captured the two suspects commenting after the murder.
Police said Fleener made a sarcastic comment, saying “oh my hand!” He then told Johansen, “we did good, bro,” and high-fived him after the two looked into a drawstring bag that appeared to have money in it.
Johansen was arrested near the homeless camp where he lives in Milwaukee, and Fleener surrendered to Milwaukee police, who turned him over to the Greendale PD.
