Almost a year later, two more
children, Nilda Cartagena, 13, and Heriberto Marrero, 15, disappeared
from the same area, only to be found strangled to death near the
Whitestone Bridge on June 21, 1989.
Lisa Ann Rodriguez was taken on June 14, 1990. She was found dead, her
body dumped along the Hutchinson River Parkway.
Three months later, 10-year-old Jessica Guzman vanished only to be found
strangled near the Bronx River Parkway.
His request to a young friend to
follow the tracking dog and report what it found prompted police to
elevate his status from “person of interest” to “suspect.”
When they looked into his background, their suspicions were confirmed.
Henriquez at first denied knowing 21-year-old Lisa Rodriguez. But when
confronted with a picture of Rodriguez and asked about a date they had
had, Henriquez admitted knowing her and claimed he never saw her after
the date.
He told children that he was an undercover federal narcotics agent, and
he often bought them video games and toys. Henriquez liked to brag about
his sexual prowess, officials told the media.
Detectives Irwin Silverman and Gus
Papay served as the chief investigators of the case.
“I lived with this case every day, every night,” Irwin later told the
New York Daily News. “We checked out Alex from the day he was in his
mother’s womb. Gus and I went into everything in his whole life.”
It was that detailed investigation that cracked the case.
The evidence against him was largely circumstantial, however.
A police expert, Francis X. Callery, testified that three strands of
hair found on Bello, matched that Henriquez. Using charts and slides
that dramatically showed the similarities, he also said that fibers
found on three victims matched those in a vacuum cleaner in Henriquez’s
apartment or on a spool of red thread that according to other testimony
had been in his apartment.
Most damning, though, was his
attempt to have his nephew make phone calls to the media pretending to
be the killer.
“He wanted me to pretend like I was the killer,” the nephew, John
Anthony Ramirez, testified. “He told me to disguise my voice, to be careful not to get caught, to keep it a secret
between me and him.”
When Ramirez asked for more
details of the crimes, Henriquez slipped up and told him things that
only the killer would know — such as a rip in the training bra that
Jessica was wearing. That fact had not been made public.
A note Ramirez was to use as a script also emerged during the trial:
“I called you to worn you put you didn’t listen. I will strik again were
when how. But soon my this time youll belive me . . . I will stop when I
reah Big 13. So far luckey 7 ha ha ha ha hang up.”
After a six-week trial, Henriquez,
who did not take the stand, was convicted of the murders of Jessica
Guzman, Lisa Ann Rodriguez and Shamira Bello and sentenced to the
maximum term of 75 years. He has not been charged with the other two
killings.
