An engineer who met Cal Poly pupil Kristin Good at college per week earlier than she vanished is on a quest to search out her physique – and believes new cutting-edge soil examination expertise factors them to the yard of her killer’s mom.
Good disappeared in 1996 after an off-campus get together and was final seen by one other Cal Poly San Luis Obispo pupil Paul Flores, who walked the 19-year-old to her dorm room. He was convicted in October 2022 of her homicide.
It has been 27 years since Kristin went lacking, however her physique has by no means been discovered, regardless of repeated searches of Paul Flores’ backyards and the backyards of his mother and father Ruben Flores and Susan Flores.
Kristin’s mother and father Stan and Denise Good have discovered solace in Flores’ responsible verdict, however stated it is not sufficient. They wish to carry Kirstin house and lay her to relaxation.
And Timothy Nelligan, an environmental engineer from San Clemente, who met Kristin at college, needs to assist her household discover closure.
Nelligan, together with a scientist and a FBI research-chemist-turned-professor, have joined forces and say utilizing new expertise referred to as soil vapor sampling could have detected human stays buried behind Susan Flores’ house.
He made the declare regardless of a number of prior searches and digs going down on the property, which yielded no hint of Good.

The Kristin Good case remained unsolved for many years, however a real crime podcast ‘Your Personal Yard’ renewed public curiosity in 2019 and jolted native police who later credited the host Chris Lambert with serving to to crack her case.
Each Paul and his father, Ruben, have been charged in reference to Kirstin’s loss of life, with prosecutors saying that Ruben helped his son by stashing her physique underneath their yard deck for years. The pair have been suspected of transferring her stays as soon as suspicion began rising in 2020.
After a prolonged trial, Paul Flores was discovered responsible of homicide in October 2022. A separate jury acquitted Ruben Flores, 81, of being an adjunct.
In March 2023, the youthful Flores was then sentenced to 25 years to life in jail for the homicide of Kristin Good.
However nonetheless the seek for Kristin’s stays continues and even the San Luis Obispo County’s Sheriff’s Workplace has refused to shut the case.
‘We do not take a breath. We don’t put this apart. We proceed to pursue this till we carry Kristin house to the household,’ Sheriff Ian Parkinson stated after Flores’ trial.

Per week after Flores’ sentencing, Nelligan and his crew returned to Flores’ mom’s (pictured) neighborhood in Arroyo Grande. That they had already performed analyses of the soil in 2020 and 2021. Every time, it indicated that there is a physique within the floor
Nelligan met Kristin at Cal Poly when she knocked on his door asking to make use of the telephone. Per week and a half later, she went lacking and her image was everywhere in the information.
Since then, Nelligan has needed to assist the household and in November 2019, he put his engineering expertise to make use of, researching how our bodies decompose in soil.
Steve Hoyt, one other Cal Poly grad with a doctorate in environmental science who has constructed a enterprise on the Central Coast testing soil samples, and Brian Eckenrode, a retired FBI forensic scientist and knowledgeable in human decomposition, joined the crew.
Per week after Flores’ sentencing, Nelligan and his crew returned to Flores’ mom’s neighborhood in Arroyo Grande. That they had already performed analyses of the soil in 2020 and 2021. Every time, it indicated that there is a physique within the floor.
‘The info tells the story,’ Nelligan stated.
The soil vapor sampling identifies the presence or absence of unstable natural compounds (VOCs) linked to human decomposition, Nelligan defined to the Los Angeles Instances.
Eckenrode believes he has narrowed down the variety of compounds linked to a decomposing physique to between 30 and 50, though the science is highly-experimental, and stays unproven.
The knowledgeable and his colleagues say they’ve additionally been in a position to pinpoint clear variations in vapors from human decomposition and animal decomposition, in a bid to fend off claims that they’ve solely discovered a useless animal.

Every time the crew did an evaluation, they accessed the property line via Susan Flores’ neighbor Marcia Papich, whose fence borders the yards.
Of their 2023 search, Nelligan twisted a heavy-duty metallic auger into the soil close to the property line whereas Eckenrode collected the unstable natural compounds from the soil vapor right into a canister.
Just a few weeks later, the crew acquired information that lit up a bit of ‘Papich’s yard bordering Flores’ property in a wealthy reddish-orange haloed by inexperienced, with blue spilling to the farthest reaches of the multicolored sample,’ the Instances reported.
The plume map confirmed the amount and high quality of key markers within the VOC samples, Nelligan stated.
It reported that the science is unproven and has by no means been utilized in any legal proceedings, however the group is assured in its findings.
Sheriff’s Det. Greg Smith stated they’re investigating the group’s work and that investigators are additionally consulting with a scientist on the College of Tennessee, Knoxville — house of the Physique Farm — who focuses on human stays.
‘It’s intriguing if we are able to get some validation,’ he stated.
Nevertheless, the detective needed to clarify that getting a search warrant for Susan Flores’ property would require possible trigger and that it is nonetheless a problem for researchers to indicate there are ‘seemingly’ human stays.
There are additionally issues the expertise that would finally uncover Smarts’ stays could possibly be utilized by Flores’ legal professionals to problem his conviction.
Susan Flores has by no means been charged in reference to Paul’s crimes and maintains that he did not kill Kristin nor does she or her household know the lacking pupil’s whereabouts.
Harold Mesick, the lawyer who secured a not-guilty verdict in Ruben Flores’ accent expenses, advised the Instances that the concept that a physique could possibly be in Susan Flores’ yard is ‘ludicrous.’
He added that nothing had ever been present in a number of searches of each Susan and Ruben Flores’ yards, and stated that authorities brought on $30,000 in harm to Ruben Flores’ property by digging under his deck. That search additionally turned up nothing.

Smith stated they only wish to watch out not to offer any choices for appeals that would undermine Paul Flores’ homicide conviction.
‘We’re strolling on skinny ice right here, and earlier than we go any additional, we wish to make that ice thicker,’ Smith stated. ‘Does a courtroom contemplate soil vapor proof?’
Again in 2020, the evaluation consisted of pushing a soil vapor probe, with a protracted, straw-like attachment, about 3 to five toes into the soil.
Any gases the probe encountered have been then vacuum-withdrawn and picked up, then sealed in a canister. The extracted unstable natural compounds have been then despatched for evaluation at a San Luis Obispo laboratory operated by Hoyt.
What confirmed up when these compounds have been represented with colours on a plume map and in contrast with dozens of control-point samples of close by soil indicated the presence of a decaying physique, Eckenrode advised the Instances.
They examined for carbon tetrachloride, trichlorofluoromethane, dimethyl disulfide, toluene, chloroform and different chemical compounds related to the decomposition of human stays.
Nelligan, together with a scientist and a FBI research-chemist-turned-professor, have joined forces and say utilizing new expertise referred to as soil vapor sampling could have detected human stays buried behind Susan Flores’ house.

Eckenrode, who has 23 years expertise as an analytical chemist with the FBI, has hung out analyzing decaying stays on the College of Tennessee’s Anthropology Analysis Facility, often known as the Physique Farm.
He stated it’s doable to inform the distinction between the decomposition of human and animal stays – and likened the distinction in patterns to flying over Buffalo and New York Metropolis; every has completely different constructing heights and layouts.
‘Consider the completely different cities like completely different animals,’ he stated. ‘We wish to discover that one cityscape that’s human and solely human.’
Eckenrode stated the evaluation of a number of samples from Papich’s yard factors to a physique decomposing on the Flores property.
Kristin’s mom Denise was requested about the potential of VOCs that would point out the presence of a physique on Susan Flores’ property, to which she replied: ‘There should not be human stays in anyone’s yard.’
They stated they help the work being accomplished, however is not going to get too emotionally invested.
‘It’s important to me,’ he stated. ‘Others are attempting to carry Kristin house.’
‘An important factor for our household is the flexibility to carry Kristin house to be buried within the presence of those that love her,’ stated Denise Good, who famous she and her husband had met with the crew and seen their analysis.
A number of searches for Kristin’s physique have been accomplished. The FBI and San Luis Obispo County sheriff’s deputies in 2016 excavated a hillside above Cal Poly in addition to two undisclosed places.
5 years later, cadaver canines and ground-penetrating radar have been used to look Ruben Flores’ yard, which had been searched within the Nineties.
