Wife of Matthew Gaudreau, sister-in law of NHL star Johnny Gaudreau, is pregnant amid brothers' death in cycling accident

 The wife of Matthew Gaudreau and the sister-in-law of NHL star Johnny Gaudreau is pregnant amid the brothers' death in a cycling accident in New Jersey on Thursday night. 

Madeline Gaudreau is five months pregnant, with a due date of December 31 for the couple's son, Tripp, per PEOPLE.  

The Gaudreau brothers were believed to have been cycling on the eve of their sister Katie Gaudreau's wedding when the fatal crash occurred just before 8:30pm in Oldmans Township, Salem County. 

The two were struck and killed by another vehicle, driven by 43-year-old Sean M. Higgins of Woodstown, New Jersey, who is suspected of being under the influence of alcohol at the time of the crash. 

Higgins has been charged with two counts of vehicular homicide with no bail or bond. The cancellation of the wedding was first reported by Page Six.

In documents seen by DailyMail.com, Higgins admitted to cops that he drank '5-6 beers' before getting behind the wheel of his Jeep Grand Cherokee and crashing into the back of Johnny and Matthew on Thursday night. 

The wedding ceremony between Katie and her fiancée, Kevin Joyce, was due to take place at the Parish of St Mary - St Mary's Roman Catholic Church in Gloucester City starting at 1:45 p.m., per the couple's page on The Knot.

A black tie cocktail hour and reception over six hours of Friday night was scheduled for The Lucy by Cescaphe in Philadelphia.

When the wedding will be postponed to is unknown at this time.

Officers also allege that Higgins showed signs of being drunk and admitted to drinking 'prior to and while operating his vehicle'.

While reeking of alcohol, Higgins is said to have told them that 'his consumption of alcoholic beverages contributed to his impatience and reckless driving.'

A GoFundMe has been started to help with the family's upcoming expenses. Madeline's baby registry can also be found here.
