Evil Hennessy's background to be checked for links to Deirdre Jacob case

Gardai are expected to explore any links between suspected abductor and killer Mark Hennessy and the cases of missing women in the Leinster region over the past 20 years.     On July 28, 1998, trainee primary school teacher Deirdre Jacob vanished without trace in Newbridge.   She was last seen at about 3pm, outside the gate of her family home, at Roseberry.  

It's believed that Filipino student Jastine Valdez (24) was murdered, probably by strangulation, on Saturday evening shortly after being abducted by Hennessy from a roadside in Enniskerry.

Garda sources said the DNA profile of Mark Hennessy (40), will now be crosschecked on the DNA database for any links to unsolved historical or recent sex crimes, the Irish Times is reporting today.     The newspaper said a review is also set to be carried out into Hennessy’s life to establish if he may be linked to any cases in which women vanished without trace in Leinster over the last 20 years - including Deirdre Jacob, Fiona Pender, Annie McCarrick, Jo Jo Dullard, Fiona Sinnott, Eva Brennan and Ciara Breen.   DNA samples were also gathered during the investigation into the murder of Raonaid Murray (17) in Glenageary, south Dublin, in 1999. It will be among the cases Hennessy’s profile is checked against.     Garda sources told the Irish Times that what appears to be the sexually motivated abduction of Ms Valdez was highly unlikely to be a first-time violent offence. There is no known link between Ms Valdez and Hennessy.
