MISSING Esra Uyrun’s ­anguished sister has asked gardai to check if psycho Mark Hennessy could have murdered her too.

The 40-year-old monster abducted and strangled pretty Jastine Valdez, 24, last ­Saturday before he was shot by a garda on Sunday night.

Married dad-of-two Hennessy, of Bray, Co Wicklow, was tracked down by cops after witnesses saw the Filipina student being bundled into his SUV in nearby Enniskerry.

Gardai are now probing whether the thug — who was on a drink and drugs binge last weekend — may have been behind a string of disappearances of young women.

Relatives of missing Esra Uyrun have revealed they are among the families left wondering if ­Hennessy, dubbed ‘The Beast of Bray’ by locals, had struck before.

The 38-year-old mother-of-one disappeared after leaving her home in Clondalkin, west Dublin, to go shopping seven years ago.

Esra, originally from Turkey, has not been seen since she went out on the morning of February 23, 2011. Her car was later located on the promenade in Bray.

Speaking to the Irish Sun last night, Esra’s distraught sister Berna Fidan told how she has contacted gardai to ask of possible links between the cases.

She said: “It is distressing. Somebody saw this man take this woman but then who says he hasn’t done it before and nobody has actually seen him do it? And how long he has been doing it for? We don’t know.”

Heartbroken Berna has been tirelessly campaigning to try to get to the bottom of the mystery.

Esra’s family insist she did not take her own life or deliberately vanish. Berna does not believe that her sister drove her car to Bray.

A set of car keys with a photo of Esra and her son Emin on the keyring were handed in to a chip shop in Neilstown — very near her Clondalkin home — six months after she disappeared.

Seven years on, London-based Berna says her distress has only got worse.

And with Hennessy’s horror crime sparking fears he may have been a serial killer, Berna is anxious to know if cops believe he could be behind her sister’s disappearance.

She highlighted how the two cases happened in the “same sort of vicinity” — with Hennessy originally from Ballybrack, Dublin, just 6km from Bray.

Berna added: “I finally got a response back today from An Garda Siochana and they told me Esra’s case has been forwarded to the investigation team looking into the suspect’s history.

“They said there’s nothing yet to suggest a connection between the cases but they’d be back in touch if this changes.

“I had emailed them ­several times about what is going on over there at the moment . . .

“I just wanted to know if it is being considered as part of the investigation because it was in the same sort of vicinity.”

And long-suffering Berna told how maniac Hennessy’s rampage has plunged them into “more pain”.

She said: “My mum doesn’t know about what’s going on over there and I wouldn’t tell her because it would just distress her even more.

“It is obviously a concern for all of us, not just our family.

“I’m sure there are plenty of other families that are sitting there wondering, ‘What if?’

“I’ve had so many messages sent to me, ‘Have you read this news?’

“It brings it all back, it never leaves us anyway.

“Esra is spoken about every single day, somebody is always asking for Esra, she is mentioned all the time.

It has never left us but when something like this happens, it just brings the pain even more to be honest.” A Garda spokeswoman confirmed that Esra’s case is a live, ongoing probe.

Meanwhile, fresh searches were carried out yesterday relating to Jastine’s abduction and murder.

Officers are trying to locate her blue shoulder bag and Apple iPad Mini near where her body was found at Puck’s Castle Lane, Co Dublin, last Monday afternoon.

School friend Kate Ordinario paid tribute to Jastine, saying: “She’s so kind, caring and loving. I remember her compliments to me when I was in Junior High School.”
