Here's hoping nothing happened and the journalist just took a nap at a hostel or something, but the optics are quite bad, it's a lot of coincidences which look pretty nasty.
Ships aren't build with built-in scuttle capabilities, military submarines can be scuttled because you can blow yourself up.
The likely scenario is that the submarine has failed, she either died before she could escape or the more likely scenario is that Madsen panicked, saved himself and left her behind to die.

Submarines are. Ballast tanks plus leaving a hatch open.
Also, the sub didn't sink until 11am the day after. She did not plan on an overnight trip in the sub. That's why I think there's more to this story than an accidental sinking.
They were looking for the submarine for hours before it showed up and sank in front of eyewitnesses. It was in the news already at that stage. I think he may have panicked when he learnt that everybody was looking for him and the woman and then sank the sub. One eyewitness saw him in the tower, then he went down into the sub, then back up, and then it sank. My guess would be that he went down and pushed the submerge button, went back up and got himself "rescued" by a passing boat.
The vast majority of small boats have through hole fittings for things like the heads (toilet) or cooling water intake for the engine. Opening the valve and smashing the pipe off is a trivial way to sink the boat. Larger ships will have similar fittings though the sinking will take longer. As noted by your others there's ways to intentionally flood a submarine too even if they're not intended for that purpose.
Guess it depends upon you definition of "Small Boat". Certainly your standard mono hulled yacht will sink rapidly if you fill it with water (which is purposefully done on occasion, if sailing across an ocean and major damage forces you to abandon ship to another vessel the insurance company may ask you to sink the boat. It's not worth the costs required to salvage and is a danger shipping if left afloat).
He could just claim that they both abandoned the submarine and then got separated. What benefits are there to make a elaborated plan?

He claimed earlier that she was dropped off many hours prior to the incident. He apparently has a new and different story now, though the police aren't saying what it is.
He can't claim they both abandoned the submarine when it sunk, as there were eyewitnesses to that event.
What is likely, given what's known at this point? I don't see some more likely scenario. Her body wasn't on the submarine, and the eyewitness account of the sinking supports the idea of a deliberate scuttle. The police say it looks deliberate as well.
that makes this quite unlikely
The police may know much more than they have told the public. They very quickly arrested the man, and they must have had a good reason to do so. The court also jailed him for a couple of weeks, based on evidence presented behind closed doors - the reason for the closed doors being "of respect to the family". There was some evidence presented which would have been of harm to the family, more harm than the public fact of suspected murder. The police may already know most of the story and only needs some time to build the case for the judge.
Investigators also suspect that the sub was scuttled to conceal evidence.
You probably meant "divers with a basic SCUBA certification" (open water, ~30ft depth and conditions similar to your previous dives)
12m and 20m are basic recommendations listed here. I seem to remember 30ft and 100ft (plus following tables / computers) as the recommended limits.
I have a recreational dive certificate issued by NASDS Australasia in 2000. Looks like NASDS Australasia has since faded from view, and NASDS USA joined with SSI around 1999.
It appears SSI adhere to ISO 24801[1]

Who is "they"? There is not some scuba sheriff who magically appears and stops you from going as deep as you want. Get some gear, swim out, and dive. How deep you go is 100% up to you.
Also, dive computers make the whole thing very safe by tracking exactly how long and how deep you can stay without needing any lengthy nitrogen releasing safety stops. As a recreational diver with a bit of experience, you can feel very confident going down to 160 feet (maybe even 200?) as long as you listen to your dive computer.
You can see tables of the no decompression time: http://elearning.padi.com/company0/tools/RDP_Table%20Met.pdf
The calculations are quite confusing do to manually, but your computer does them great, and in realtime, and for your exact depth & time. So, like I said, as long as you follow your computer, the risk for nitrogen narcosis or any other problems is very very small.
But I still argue the point: the depths that you will suffer seriously from nitrogen narcosis are beyond how deep you could even go on 1 tank + no decompression time.
Once you get to 160 ft you only have a few minutes at that depth, so realistically you couldn't even go deep enough where nitrogen narcosis would be a big problem.
So I still stand by my statement: if you have only 1 tank, and follow your dive computer's guidance, your risk of anything bad happening to you on a dive is slim to none.
They're not cheap, but they're also not all that expensive.
So, if you're "uncertified" and you somehow managed to get yourself a filled air tank, then my point still stands: you can go down to however deep you want.
And the basic open water certification is not much more than a rubber stamp. Anyone can get it as long as they pay their $100 to PADI or whoever else.
I don't get how anyone could dive for fun, it's scary down that deep :)
For anyone free diving at that depth, I'd encourage you to ensure there's always someone nearby that is capable of rescuing you.
Shallow/deep water blackout[1] is certainly dangerous with a buddy, but it's deadly if you're alone.

Rescue is related. I doubt anyone could pull somebody out that's passed out at that depth. You're just not going to have enough air. I had to help someone out of a pool once and the only way I was able to manage was by walking along the bottom with them on my shoulders to shallower area. They panicked and tried to climb me, pulling me under if I did anything else
Well done helping that person. Rescuing a free diving blackout has the benefit (for the rescuer) of an unconscious victim.
> In the afternoon there have been divers on the submarine, lying on seven feet of water. It has not been possible to enter the submarine, either being stabilized on site or rescued and towed to port before it will be possible. This will probably happen during Saturday.
They will attempt to either enter the sub on site or tow it back to port today (Saturday).
