The vast majority of murder cases are "only" circumstantial cases.
DNA is not needed to convict someone of murder, though of course it's best if they have it. Ditto having a body.
- A jury (any jury) will have to wonder why SM was calling HE that night/morning and why HE then told her roommate SM called hr and wanted to get back together.
- A jury will have to wonder why HE's cell phone, known to be with her (verified with a phone from earlier in the evening when on a date) was pinging and showing a GPS trail leading to PTL at the exact same time as a black truck.
- A jury will have to wonder why HE's vehicle was left at PTL and why her cell phone stopped transmitting after arriving at PTL at at the same time as the black truck.
- A jury will have to wonder why HE was suddenly in touch with SM, and why SM lied and said 'nope not been in touch with her since a couple months ago' then seen on video at a payphone that very night same time as HE gets a call from a payphone.
- A jury will have to wonder why HE left her apt and how HE's car came to be at PTL at the same time as that black truck, then was never seen again.
