First Shane needs to take enough undergrad science coursework (including retaking any class he earned a C- or lower) to raise his sGPA into 3.2 range. Grade replacement is not allowed and both original & retakes must be included in all GPA calculations.
Then Shane needs to enroll in a grade-enhacing post bacc programs, preferably at a program associated with a medical school. If possible, he should enroll in a Special Master’s Program (SMP) which typically require a GPA and sGPA >3.2 and MCAT score of 500+. These are grad degree programs that mimic the rigor of the first year of med school.
If he finishes a SMP in the top 15-20% of the class and with a GPA >3.7, he has about 50-50 chance of getting admitted to med school, assuming he has checked off all the EC boxes.
If Shane moves to TX and waits 10 years, he can apply for the Academic Fresh Start program and have his undergrad record erased. He will have to start over with a new BA/BS degree and go from there. Medical schools outside of TX do not recognize the Fresh Start program and will include both his current grades and new grades when calculating his GPA.
Overseas med schools may be a possibility, but realize that the odds of Shane flunking out at one are very high (it’s how their business model is structured–accept lots of MS1s, flunk 2/3rds of them over the next 2 years because the schools don’t have enough clinical training slots…) Also the odds of ever gaining any US residency for US IMGs are quite poor. (Less than 50-50.)
Forensic pathology is not a residency level specialty. It’s a fellow level program. Shane would need to first complete a 4 year general pathology residency, then apply for and be accepted into a 1 year fellowship program in forensic pathology.

So there are no guarantees he’ll be able to match into forensics, though matching into general pathology is not especially competitive.
Shane needs to look at other career options since his pathway to becoming a pathologist is extremely narrow and highly unlikely.
Medical technologist in a forensics lab. Requires a BS in CLS or forensic science.
Medical examiner assistant/autopsy assistant. Requires BS or MS in biology with coursework in anatomy, physiology, microbiology, pathology, ochem, neuroscience, clinical laboratory sciences. Certification by American Society for Clinical Pathology is required for employment. There are specific grad programs that prepare students for careers as ME/autopsy assistant.
