Police: Wisconsin Shooting That Left 6 Dead Was a Murder-Suicide

A weekend shooting that left six people dead in an apartment, including twin baby boys, was a murder-suicide committed by the father of the children, police said Wednesday.

Ambrosio Analco killed infants Isaiah and Argenis Analco, his ex-girlfriend, Nicole McAffee, and two other people before shooting himself Saturday, police Chief Tim O'Neill said. He also wounded his 1-year-old daughter, who was found in a van outside the home in Delavan, in southeastern Wisconsin.

Although investigators were still waiting for the results of tests on forensic evidence, O'Neill said "all agencies are confident this was a murder-suicide."

O'Neill called the shooting the most tragic event his city has seen.

"It's been terrible for Delavan," O'Neill said. "But you know what? This community is resilient."

A cousin has said Analco, 23, had gone to the house to drop the kids off with McAffee, 19. Also killed were McAffee's sister Ashley Huerta, 21, and McAffee's friend Vanessa Iverson, 19.

Analco's daughter, Jasmine, was shot in the chest. She was in good condition Wednesday at the University of Wisconsin Hospital in Madison, officials there said.

Walworth County Sheriff David Graves praised the officers and paramedic who rescued Jasmine from a van outside the duplex, carried her to safety and tended her wounds.

The officers visited in her in the hospital Tuesday night, he said.

"She obviously lost some family that evening, but I think she gained some family," said Delavan police Sgt. Todd Wiese, who helped rescue the child. "Lots of uncles on the department who are going to adopt her, for lack of a better term."

Huerta's husband, Gaspar, escaped the shooting by jumping from the duplex's second-story roof and called police. His brother has said that Analco and McAffee fought often and that Analco threatened to kill everyone in the apartment if he found McAffee cheating on him.

Marco Pastrana, Analco's 21-year-old cousin, said he still believed Analco was innocent, despite what police said. Analco had been at Pastrana's home Saturday evening and asked him to come with him when he dropped off his kids.

"Why would he ask me to go if he was going to do that?" Pastrana said. "I don't think he would kill me."

Police met with the victims' families earlier Wednesday, O'Neill said. He did not comment on their reactions and left the news conference without taking questions.
