Opinion

Supreme Court of Florida ____________

No. SC2023-1003 ____________

JOSEPH ZIELER, Appellant,

vs.

STATE OF FLORIDA, Appellee.

April 16, 2026

PER CURIAM.

The appellant, Joseph Zieler, was sentenced to death for the

1990 first-degree murders of R.C. and L.S. in Lee County. Zieler

was unknown to investigators of the double homicide until 2016,

when his DNA was entered into the Combined DNA Index System

(CODIS) and triggered an alert. This is Zieler’s direct appeal. We

have jurisdiction. See art. V, § 3(b)(1), Fla. Const. As we explain,

we affirm Zieler’s convictions and sentences. BACKGROUND

Events Surrounding the Murders

Jan C. lived in a condominium in Cape Coral with her

daughter, 11-year-old R.C., and a friend/colleague, 32-year-old L.S.

L.S. had recently moved into a spare bedroom in the condominium

to share living expenses. On the evening of May 9, 1990, Jan went

to her boyfriend’s home to watch a basketball game on television.

L.S. and R.C. encouraged her to do so while they remained at home.

Both were in their beds when Jan left.

Jan, who had to get up early the next morning for work at a

local hospital, had intended to return home after the game

concluded. However, she fell asleep and did not wake up until

4 a.m. Jan then rushed home to get ready for work, and upon

arrival, discovered that the front door that had been locked only at

the deadbolt was also locked at the broken door handle. When the

broken door handle was locked, it prevented entry from the outside.

Jan did not immediately sense that there was a problem;

instead, she thought that L.S. probably forgot about the broken

door handle and mistakenly locked it before going to bed. Jan then

walked around the unit to the patio and discovered that the sliding

-2- glass door was open, and the vertical blinds were blowing out the

door.

After Jan entered the previously organized unit, she began to

notice signs of disarray. She went upstairs and first reached the

door of L.S.’s room where she saw L.S.’s nude body on the bed.

When she called out to L.S., she did not get a response. Jan raced

to the other bedroom and found R.C. face down on the floor at the

foot of the bed. R.C.’s legs were spread apart, a vibrator was on the

floor between her legs, and a pillow was located underneath her

stomach. Jan called 911 as she began to administer CPR to R.C.

As Jan performed CPR on R.C., she observed nasal congestion that

suggested to her that R.C. had been crying a lot. Jan heard R.C.’s

lungs aspirate.

When law enforcement arrived, evidence indicated that an

intruder entered the condominium, attacked, sexually battered, and

suffocated both victims, and ransacked the unit.

L.S. was found lying in her bed on her right side with a pillow

partially covering her head. She sustained extreme injuries to her

anal cavity and significant bleeding. There were scratches on her

body, and a broken fingernail on her hand appeared to be a

-3- defensive wound. An open pornographic magazine was found on

her bed. Injuries to the mucosa of her lips and the presence of a

pillow suggested that she may have been smothered to death.

The search of L.S.’s room revealed an empty wallet with items

missing, and an empty watch box that previously contained a watch

that L.S. recently bought as a present. The watch was never

located.

R.C. had bruising and scrapes on her cheekbones and her lips

were purple, which indicated that she had been suffocated. There

was significant bleeding from her vaginal area. She had a cut in the

middle of her back, possibly caused by being dragged across sharp

wood at the foot of the bed. R.C. also had an abrasion on her left

thigh which was likely caused when her underwear was ripped off.

A pair of ripped underwear was found in the room. R.C.’s wounds

indicated that there was a struggle before her death.

The Autopsies

Medical examiner testimony indicated that both victims died

as a result of asphyxiation. The bodies of both victims showed

signs of a struggle and signs of sexual battery. L.S. suffered

extreme anal injuries and bleeding, consistent with an object

-4- penetrating her anus. R.C. suffered injuries to her vagina that

caused significant bleeding and were the result of penetration by an

object. The penetration of L.S. and R.C. occurred

contemporaneously with their deaths, but the medical examiner

was unable to determine with certainty whether penetration

occurred before or after their deaths. However, the initial lead

detective testified that in his experience, based on the amount of

bleeding from the anal cavity of L.S. and the vaginal area of R.C.,

they were likely both alive when they were penetrated.

Various items of evidence including genital swabbings and

hair evidence were obtained from the victims’ bodies.

DNA Evidence

During the investigation, DNA testing excluded many persons

of interest. Evidence submitted for DNA testing in 1990 revealed

the presence of sperm cells in the genital gauze swabbing, vaginal

slides, and anal slides obtained from R.C., the genital gauze

swabbing obtained from L.S., and a pillowcase and bedsheet that

were found in the bedroom with R.C.

The bedsheet, the pillowcase, and the genital swabbing from

R.C. all tested positive for semen in a sufficient quantity to develop

-5- a DNA profile. These items were first tested using RFLP testing in

1990, then they were sent for additional testing in 2000 and again

in 2012 due to advancements in DNA technology.

RFLP DNA testing performed on the pillowcase and on the

genital swabbing from R.C. yielded DNA profiles that were

consistent with one another. The sample size from the genital swab

indicated that the semen was deposited onto R.C. as opposed to

being transferred onto her. At the time, the results of these tests

were not entered into CODIS, which only accepts STR DNA test

results. The genital swabbing obtained from L.S. and the anal

swabs obtained from R.C. were insufficient for further testing.

STR DNA testing was conducted in 2000. The genital

swabbing obtained from R.C. and the pillowcase retrieved from

R.C.’s bedroom yielded partial DNA profiles, and a cutting from the

bedsheet yielded a complete DNA profile. The three DNA profiles

were consistent with one another. The profile from the bedsheet

was entered into CODIS.

In 2008, STR DNA testing was conducted on hairs obtained

from L.S.’s body. Among several hairs and debris or fibers, the

analyst found four hairs suitable for DNA testing. Two of the hairs

-6- were very light in color and yielded no DNA. The other two hairs

were darker in color and yielded partial DNA profiles that were

consistent with one another. Each of the four hairs was less than

15 millimeters long and, due to the small size, completely

consumed during the DNA testing.

In 2012, in response to further advancements in DNA

analysis, the bedsheet was resubmitted for STR DNA testing. The

results revealed a complete DNA profile that was consistent with the

profile obtained in 2000. The profile was entered into CODIS.

In 2016, law enforcement received a CODIS hit, or lead, in the

L.S. and R.C. double homicide case. Zieler’s DNA, obtained as a
