After more than three decades, justice has caught up with the gunman who executed a Bronx couple in front of their young son, authorities announced. William Antonio Solis, now 62, was apprehended in Florida and charged with the brutal 1993 murders of Luis Guerrero, 31, and his wife, Danis Sime, 28. The couple was tragically bound and shot in the head during what was intended to be a robbery in their Morris Heights apartment.
The horrific crime left a lasting impact, particularly as the couple’s orphaned toddler was discovered outside, calling out desperately for his father. This heartbreaking detail drew significant media attention at the time. The case, which had remained unsolved for years, recently gained momentum thanks to the diligent efforts of NYPD detectives and federal investigators who utilized a fingerprint found on duct tape to identify Solis.
Manhattan US Attorney Jay Clayton expressed the relief and closure brought by Solis’s arrest, stating, “For more than 30 years, this Bronx double murder has haunted a family and the people of New York. That ends today.”
According to federal prosecutors, Solis, along with two accomplices whose identities remain undisclosed, orchestrated a “planned robbery” targeting Guerrero, who was known to be involved in drug dealing. The fateful event occurred on June 21, 1993, forever altering the lives of the victims’ family and lingering in the collective memory of the community.
“That ends today.”
Federal prosecutors said Solis and two accomplices, who were not publicly identified, cooked up the “planned robbery” of Guerrero, who was a drug dealer, at the apartment on June 21, 1993.
Guerrero showed up thinking he was there to sell two kilograms of cocaine — but Solis and the two other brutes instead aimed a gun at him and threatened to open fire if he didn’t follow their instructions, according to court documents.
When he refused, the trio wrestled Guerrero to the ground and restrained his hands with a wire hanger and duct tape, prosecutors said.
One of the perps then hauled Sime and the couple’s tot, who were waiting in their car outside, into the apartment, and then she was also tied up with duct tape, prosecutors wrote in a pre-trial detention letter to the judge.
“After a discussion about what to do, the defendant and his co-conspirators decided they had no choice but to kill Guerrero and Sime,” the letter states.
Solis then allegedly “stepped into a leading role,” shooting Sime in the head as she lay on a bedroom floor and firing at her husband while he was on the living room floor, the feds said.
The alleged killers took the child with them as they drove to the couple’s home, which they ransacked for drugs and money before leaving the orphaned boy alone in the apartment, prosecutors said.
The tot was later found by a neighbor standing on the lawn in front of the apartment, according to a Post article printed at the time.
“He was screaming ‘Daddy, Daddy,” neighbor Chris Anton told The Post back then.
The victims’ bodies were found about 24 hours later.
Solis, a Dominican Republic native who became a US citizen in 2001, left the Big Apple about 18 months after allegedly carrying out the double-murder and landed in Tampa, Fla. — where authorities picked him Thursday, the feds said.
A fingerprint pulled from the duct tape helped crack the case when investigators matched it to Solis in June 2025, according to the detention letter.
“As alleged, William Solis spent decades hiding in plain sight more than a thousand miles from where he viciously murdered the Guerreros in front of their young child,” Homeland Security Investigations Acting Special Agent in Charge Michael Alfonso said in a statement.
“This arrest is the result of years of meticulous investigative work by dedicated special agents and task force officers who refused to let this case go cold.”
It’s unclear if the two co-conspirators have been arrested. The Manhattan US Attorney’s Office declined comment.
Solis was charged with two counts of intentional killing while engaged in a narcotics conspiracy, which carries a maximum prison sentence of life or even the death penalty if he’s found guilty.
“Today’s indictment sends a clear message: the NYPD will always work to make sure criminals are held accountable, no matter how long it takes or how far they may run,” said NYPD Commissioner Jessica Tisch in a statement.
