More than three months after an alleged armed home invasion in the city's Island neighborhood, one of four suspects has been arrested — in Wisconsin.

Milwaukee police arrested Shawndell J. Zapata, 17, of Butler, without incident May 1, Butler police said.

Sgt. Jeremy Walters and a Butler County sheriff's deputy flew to Wisconsin Wednesday and returned with him Thursday.

Zapata, who is charged as an adult, was arraigned on charges of burglary, robbery, conspiracy and terroristic threats. He is being held in the Butler County Prison without bail.

Police had been looking for the teenager and two others — Lamont A. “Butt Butt” Franklin, 18, of Butler and Maurice A. “Little Philly” Franklin, 27, of Freeport — since March 12 when they got arrest warrants for the trio stemming from the February incident at a home on the 300 block of Negley Avenue.

On March 18, they got another arrest warrant for a fourth suspect, Sarah E. Fox, 20, of Ironton, Ohio.

The warrants were issued as part of an investigation into a suspected burglary and robbery at the Negley Avenue home.

A 36-year-old woman told police three males forced their way into her house the morning of Feb. 16, investigators said. She said one of them held her down while another one held down her 14-year-old son, who lives with her.

The boy reported one of them also had a handgun. Police suspect it was Maurice Franklin with the gun, which has not been recovered.

A third suspect, the woman said, went upstairs and confronted her adult daughter and the daughter's ex-boyfriend. Detectives believe the 23-year-old ex-boyfriend was the target of the home invasion.

The suspected robbers thought the man had “a large amount of money,” according to charging documents.

The trio left and no one in the house was injured. The victims, police said, did not immediately report the incident.

Around 6:30 a.m. that day, police discovered Lamont Franklin with a gunshot wound to his right side near the lower abdomen. He was found at his sister's house on Brown Avenue, where he also lives.

He was treated at a Pittsburgh hospital for the gunshot wound.

Police subsequently learned of the home invasion, authorities said, and the victims identified Lamont Franklin; his uncle, Maurice Franklin; and Zapata as the robbers.

Before Lamont Franklin was released from UPMC Presbyterian hospital, a detective spoke to him about how he got shot. His account, however, was ultimately proven false, police said.

He also denied knowing anything about the home invasion, police said. Investigators believe he was shot during or shortly after the home invasion.

During their investigation, police spoke to Fox, who they identified as Zapata's girlfriend. She was interviewed Feb. 21, a day after police arrested her for driving under the influence of a controlled substance.

She allegedly admitted to being the getaway driver during the planned home invasion.

The plan, she recounted, was “to rob (the 23-year-old man) because they believed that he had a large sum of money in his possession,” documents said.

Following the suspected home invasion, Fox said her alleged accomplices got into the car she was driving. She noticed Lamont Franklin had been shot when he got in the vehicle.

Police said the woman told them she drove to Lamont Franklin's home, and she was paid $100 for her role in the crime.

On March 12, police charged Zapata, Lamont and Maurice Franklin. Like the teen, both Franklins are charged with burglary, robbery, conspiracy and terroristic threats.

Additionally, the younger Franklin is also charged with hindering apprehension and corruption of minors, and the elder Franklin is charged with corruption of minors and four counts of reckless endangerment.

The following week, police charged Fox with burglary, robbery, conspiracy and corruption of minors.

“Once I filed the charges, everyone disappeared,” Butler Detective Lt. Chad Rensel said Thursday, referring to the defendants, “and the investigation stalled.”

While the Franklins and Fox remain at large, Zapata is in custody following his arrest in Milwaukee, where police believe he has family.

Milwaukee police nabbed the teen at a home while executing a search warrant as part of a drug investigation, Walters said.

When they ran his personal information through the National Crime Information Center database, they learned of the arrest warrant in Butler, Rensel said.

Zapata was placed in the Milwaukee County Jail and eventually waived extridiction to Butler County.

The U.S. Marshals Fugitive Task Force, Rensel noted, is working with police to find the other suspects.
