Especially since the killer is still at large.It bothers me that he revealed that the children are staying at his house. IMO, that should have been kept a secret.

So what kind of gun leaves casings? Only larger guns?The casing is the part of the round that holds the gun powder an primer, it is tube shaped. The bullet is the actual projectile part of the round, think the tip of the round.
With a semi-auto or automatic firearm, yes, a casing would be ejected with each round fired...unless the firearm was equipped with a brass catcher. People use brass catchers to catch the spent casing so it can be reloaded thus, saving money on buying new rounds. IMO, It would not be practical to have a brass catcher on a gun to commit a crime...too bulky. With a revolver, the casings are NOT ejected with each shot fired.
The casings might be able to be used to ID the gun but, if my forensic understanding is correct, investigators would need possession of the gun to compare it to the casings and/or bullets.
Edited to correct typos.
@STLBlues explained this better than I could!Can you explain the casing situation a bit more?
Are the casings automatically ejected with each shot?
Why would the killer leave the casings? Time issue?
Can the casings be used to identify the killer's gun?
I would assume LE has the phones, diaries, calendars.I suspect LE has Spencer's and Monique's phones?
9mm is the most common/popular handgun caliber.Just out of interest as my awareness of guns is zilch apart from you shoot from them
What guns shoot 9mm bullets
And could the weird gait be attributed to carrying a gun on the hip or in a pocket ?
Most guns eject casings. I think revolvers do not and maybe muzzleloaders.So what kind of gun leaves casings? Only larger guns?
The killer might have left the casings for a number of reasons?
-Time issue.
-It was dark and he didn't want to turn on the light?
-He didn't think the casings could be used against him as evidence?
Size doesn’t matter when it comes to leaving casings. The type of action is what matters. A semi auto ejects the casing to load the next cartridge to the firing chamber.So what kind of gun leaves casings? Only larger guns?

Thank you for the info. So LE will need a suspected murder weapon and casings from other crimes to make a match.@STLBlues explained this better than I could!
As for the casing yes they can be used and I don't know if the killer just rushed out, didn't want to pick them up for some other reason or what, but if LE has a gun they suspect is the murder weapon they can fire it and compare the markings left on the casings to the casings left at the scene and tell if it's a match. So let's say they find a suspect and he has a gun, or he is in a car and they find a gun in the car, they can compare and tell if that was the murder weapon. Another scenario is if the gun was used in another crime, they can also compare evidence from that crime to this one and tell if the same gun was used.
Semiautomatic guns leave casings, unlike a revolver which stores them in the cylinder (spinny thing in cowboy movies).So what kind of gun leaves casings? Only larger guns?

A revolver has cartridges in a revolving cylinder, usually 6 cartridges, but it can be a different number. It revolves either by pulling the hammer back, or pulling the trigger (single action vs double action) and lines the next cartridge up with the barrel for firing. Casing are ejected manually by the shooter after firing is completed or the revolver is out of cartridges and needs to be reloaded. That’s kind of simplified.
There are other action types on handguns and long guns but most handguns are either semi auto or revolver.
Not just the ballistics, but DNA as well. There are now really effective methods at obtaining DNA from spent casings, which was successfully used in the Brown University shootings case.THE KILLER LEFT THE CASINGS
In addition to the write up I wrote just upstream about 9mm handguns, long guns and pistol caliber carbines.
The spent casings left at scene would indicate someone who's not a pro. A professional or calm intelligent killer with a suppressor (which I still maintain is more far fetched) would have picked up 3 spent casings. This is crucial. They are the only ballistic link to the murder weapon and a big deal. Some hitmen prefer shotguns for this very reason (smooth bore no matching rifling for ballistic match).
The three spent common 9mm rounds found on the scene along with 2 shots to the husband and one to the wife leads me towards a sudden shooting and hasty, sloppy retreat.
In fact many of us who reload our own ammunition, when we go to the range pick up our own brass casings. When I shoot outdoors I often do this out of habit. No pro with the proficiency to make a suppressor would leave 3 shiny casings that link him definitively to the murder weapon.
Completely agree that a semi-auto handgun was used in this crime.Semiautomatic guns leave casings, unlike a revolver which stores them in the cylinder (spinny thing in cowboy movies).
Semi auto rifles and handguns leave them, but based on the round size and practicality, were certainly talking about a handgun here.
Semi auto on the left, revolver on the right.

DbmGlock and Sig Sauer are very popular and reliable and have huge followings.
Yes, a firearm has to be modified to accept a suppressor (if it wasn't factory built that way).
To be honest, and in my experience, I don't think suppressors are as common as people think they are. I'm in my late 50s and have been around firearms my whole life. In that time, I've only seen 2 suppressors in person.
Handguns make up the majority of crime, especially in cities. A 9mm handgun is like a honda civic in terms of commonality,Thank you for the info.
Since the killer was on foot or in a vehicle parked on the street or ally, he would have chosen a gun he could conceal under his coat.
A long gun doesn't make sense.
Unless he thought he could quickly exit in a vehicle with no one seeing him. Or perhaps he hid the gun or disposed of it soon after the murder.
