THE man accused of murdering his wife in Fermanagh on a boating holiday to celebrate their up and coming 14th wedding anniversary was a controlling man who'd tired of her, yet was unwilling to accept she might divorce him, the start of his trial heard today (Tuesday, April 27).

Prosecuting QC Richard Weir further claimed what happened was "no tragic boating accident", and told the court that by the end of the Dungannon Crown Court trial, the jury would be satisfied that 44-year-old father of two, Stephen McKinney, "killed his wife".

McKinney, with an address in Castletown Square, Fintona, but living in Convoy, Donegal at the time, denies murdering his 35-year-old wife, Lu Na McKinney, who allegedly drowned during the family boating trip to Lower Lough Erne.

Her body was recovered from the water near Devenish Island within 40 minutes of her husband raising the alarm in the early hours of April 13, 2017.

Police reports indicated the weather that night was good, with very little wind, occasional cloud cover and a full moon.

The prosecution further claimed that in the wake of his wife's tragic death, Mr. McKinney gave conflicting accounts to police, authorities, family and friends as to how she came to be in the lough, after she had allegedly gone to secure the mooring ropes on their cruiser.

Mr. Weir claimed the evidence would show that it was Mr. McKinney who "caused Lu Na to be in the water".

Mr. Weir said the couple had lived a number of years in China and had returned only a year earlier to set up home in Co. Donegal, with Mrs. McKinney working in a number of local restaurants.

The lawyer said the Manor House cruiser was the second the family had hired from the Killadeas marina that April, and that prior to sailing they were given comprehensive instructions and safety demonstrations on its operation.

The first cruise was in a smaller vessel, just to see what it would be like, but the second was for three nights, commencing on April 12, 2017. Before setting off, they were advised to moor at the east jetty by Devenish Island.

Mr. Weir said there were two emergency 999 calls made by Mr. McKinney shortly after 1am the following morning, claiming his wife had "just ended up in the water".

Initially he was recorded telling the emergency operator his wife had fallen into the water after she'd gone to check on the mooring ropes, having complained the boat was moving.

When asked how she fell into the water, Mr. McKinney replied: "I don't know, she just ended up in the water", and that he jumped into the lough after her.

"I was in the water looking for her, trying to, I was trying to keep her, I was trying to keep her up. I got hold of her, but she went down, and I tried to pull her back up.

"I tried to pull her back up and she went down," then he added: "And she pulled me down".

Mr. Weir said McKinney was told to remain on the cruiser, get something warm to wear, and to put on the boat lights and await the arrival of the police.

The lawyer said when he spotted the lights of the approaching police launch, Mr. McKinney was heard saying: "Oh Lu Na, oh Lu Na. I see my wife."

The court heard it had taken police approximately 40 minutes from their Enniskillen base to reach the McKinney cruiser, and that Mrs. McKinney's body was pulled from the lough by a police officer using a boat hook.

Immediately, attempts were made to revive her.

Counsel further claimed that during the journey to the hospital and afterwards, McKinney told police his wife had complained the mooring ropes were loose, and despite his assurances, she wanted to check them.

Then, outside the hospital treatment room, McKinney said he'd "tried my best to save her ... she can't swim", that he heard "a splash and I heard 'help' and I jumped in ... I had hold of her, trying to pull her up.

"I had a hold of her ... at the boat ... she kept pulling me down ... I tried my best but I'm not a good swimmer".

Later, when told his wife was dead, McKinney allegedly revealed they had argued over the mooring ropes, and when they went out onto the jetty to check them: "I heard her shout. I went to help."

Mr. Weir claimed McKinney later told his wife's friends that she 'had slipped and fell into the water'; that he said he heard a splash and went outside, and that Lu Na was not wearing a life jacket, "as it would not feel pretty".

Counsel said in a follow-up search of the cruiser, police recovered the prescription drug Zopiclone – a sleeping-type tablet which in this instance was allegedly obtained by McKinney online.

The court heard the drug could lead to depressions, while also effecting balance, coordination and drowsiness, and that the amount found in her system was more than the normal therapeutic dose.

In conclusion, Mr. Weir told the jury: "We say this is a controlling man, who tired of his wife but was not prepared to accept she might divorce him with all the consequences that would have.

"This is not a tragic boating accident – we say he caused Lu Na to be in the water ... that he killed his wife."

The trial, that is expected to last up to 10 weeks and is set to hear evidence from up to 70 witnesses, continues tomorrow, Wednesday.
