Horrific story out of Milwaukee.

A 39-year-old Milwaukee man methodically shot and killed three of his neighbors at point-blank range last weekend at an apartment complex on the city's south side, according to a criminal complaint filed Thursday.

Dan J. Popp faces three counts of first-degree intentional homicide in the deaths of Jesus R. Manso-Perez, 40; Phia Vue, 36; and Mai K. Vue, 32. The victims were pronounced dead in their four-unit apartment building in the 3300 block of S. 92nd St. after the shooting was reported about 5:45 p.m. Sunday.

Manso-Perez and his son were walking by Popp's apartment on their way to wash clothes. They declined the offer of a beer.

Popp then asked where they were from and the father and son replied Puerto Rico.

The son later told police that Popp replied: "Oh, that's why you don't speak English. You're Puerto Rican."

Manso-Perez and his son continued to the basement where they got the washing machine started. As they climbed the stairs back to their apartment, Popp stood over them on a landing. He was armed with a rifle.

The son told police Popp pointed the gun at his father — saying, "You guys got to go" — and pulled the trigger.

….

Popp kicked down the front door, made his way into the bedroom and pointed the rifle at Phia, ordering him to leave.

Phia followed Popp, and his family inside the bedroom heard two or three gunshots. Officers found Phia dead in the bathroom. He had a gunshot wound to the head.

Popp returned to the bedroom and began to drag Mai and her two young daughters out of the apartment while the older relative and other children followed. Some were able to run outside.
