I think there is a lot of room between having 'nothing' and being able to arrest someone, or several someones.
IMO the officer is probably going through video recordings to try to pinpoint who physically approached and then left the house, and where they originally came from and where they went.
IMO that would mean reviewing commercial and doorbell footage, from all the streets around the house, over a period of many hours that night. IMO it would include tracking any vehicle or pedestrian that ended up passing by Colony Road, to eliminate it from the search...that work could take a very long time. And if they find a suspicious person or vehicle, then they would need to track where they came from and where they went, to try to identify them.
Also, trying to track the movement of any potential suspects who don't have a air-tight alibis.
Possibly also cell tower records of all the phones pinging in the area during that time period, or phones of potential suspects.
Interesting article- The following statement struck home
“...A Washington Post examination of 8,000 homicide arrests across 25 major U.S. cities since 2007 found that in half of the cases, an arrest was made in 10 days or fewer......
for cases that remained unsolved after one year, 5 percent ultimately led to an arrest...”

I think Satchie has hit the nail on the head intentionally or not, when he wrote “ the officer”. I recall that TPS has redeployed it’s full time resources to other cases, and that there is one full time officer assigned to this case, and investigators are only brought into the Sherman case as required. This is also consistent with the police practices as stated in the article ( you will recall mr. Arntfield, who is quoted in the article, coincidentally was interviewed by CTV and other news outlets regarding the Sherman case in the early days of the investigation:
“... In recent years, many police departments have reduced manpower and resources devoted to solving older cold cases, said criminologist Michael Arntfield, a co-director of the Murder Accountability Project. What used to be a cold-case unit are more likely just a cold-case detective,” said Arntfield, who founded the Cold Case Society, which helps police departments review unsolved killings.
“...You try to put your resources where you have a higher probability of solving your cases,” said Oklahoma City Police Chief Bill Citty, whose department has one cold-case investigator. “And that’s going to be, you know, a newer case....”
By now I have to believe tps has reviewed all the tapes and looked at the cell phone records and interviewed who they need to interview. It’s coming up to 3 years now.
