MURDER USA: Kevin Justin McGuigan jailed on a homicide charge after killing his mother outside St. Raphael Church

ROCKVILLE, MD. – The story of Kevin Justin McGuigan, who likely should have either been in jail or an asylum was instead living in an apartment not far from his family home, and free to come and go to do as he pleased in spite of his precarious mental health in the months that led up to him killing his mother. His family never reported an attempt to kill his brother, two years earlier, according to police. However, his mother pleaded with a District Court Judge for an order barring him from her home in 2016.

On Feb. 11, 2017, a warrant was sworn out against Kevin Justin McGuigan ordering him to stay away from and have no contact with a victim of domestic violence. The order was finalized in Montgomery County District Court on Feb. 23, 2017. He was ordered not to go near his mother’s house, her place of employment or to have any contact; in addition, he was ordered to surrender any firearms and to vacate the home.

Kevin Justin McGuigan was ordered to stay away from his mother, her home, her job by a Montgomery County District Court Judge in 2017. His mother told the Judge that her son had threatened to kill her, was abusing drugs to the point of being deranged. Jacob McGuigan, when told of his mother’s murder responded to police with the question of whether his brother did it. He told them Justin tried to kill him two years earlier.

Kevin Justin McGuigan now has free government housing in the Montgomery County jail facing first-degree murder charges for the brutal slaying of his mother, Jaclyn McGuigan.

The murder of his mother was not unexpected by Justin’s brother, Jacob, who, when he and his sister Kaitlyn were informed by police that their mother had been killed, asked immediately if it was Kevin who killed her. Jacob told police that his brother tried to kill him by strangulation two years ago.

Jaclyn McGuigan went to Montgomery County Circuit Court in 2012 and initiated uncontested divorce proceedings against Kevin R. McGuigan which was granted by Circuit Court Judge Mary Beth McCormick on Aug. 29, 2012.


In Montgomery County District Court in 2016, Jaclyn McGuigan told a District Court Judge that her son was hallucinating from the use of drugs, imagining things and was undergoing a mental health evaluation at a local hospital.

In her court filing requesting a stay away order, or peace bond, Jaclyn McGuigan wrote, that her son had threatened her with physical harm many times, and told her if she didn’t answer his questions he would kill her. She told the court that her other son, Jacob, now 18, and her daughter also needed protection from the unbalanced and dangerous Kevin Justin McGuigan.  Judge Zuberi B. Williams granted the order.

Police say that they were able to determine the following:


On December 28, 2018, at about 6 o’clock pm, Montgomery County Police responded to 911 calls to St. Raphael Church located just off of Falls Road, at 1513 Dunster Road, Rockville, Md. The calls were for an assault and when Montgomery County Police Officer Marquez arrived he found a white female who was covered with blood and laying in a pool of blood with slashings to her neck. The weapon used to kill the woman was unknown to police at the time.

One witness to the attack tried to perform CPR on Jaclyn McGuigan while another ran after the man they saw standing over her body as he jumped into a car and fled. The witness was able to record the tag number of the fleeing Honda as 5CX2535. The witnesses gave police a description of the man, that police said was a white male, about twenty-three years of age with dark hair and of average size.  Police ran the registration for the Honda and learned it came back to the victim. The police were able to immediately identify Jaclyn with comparisons to her photo on her driver’s permit.

Officers and detectives quickly learned that Kevin Justin McGuigan was often an operator of the vehicle.

In less than an hour, police found the vehicle abandoned at the nearby Falls Grove Park, not far from the scene of the murder. Police obtained a cell phone number for Kevin Justin McGuigan and dialed the number, which rang on a phone that officers could see in the Honda in the park. Officers reported that they also could see blood on the phone as well.

Police went to the home of the victim to interview Kaitlyn McGuigan and Jacob McGuigan, both adult children of Jaclyn McGuigan.

One of the purposes of the visit to the home was to inform them of the murder of their mother.

“Jacob asked immediately if Kevin killed their mother. Jacob continued that Kevin had tried to kill him by strangulation approximately two years ago,” wrote Detective Mike Kwarciany in court documents.

Kaitlyn told police that she was with her mother and Kevin earlier in the day and at about 5:30 pm her mother and brother left the home in the Honda to an unknown location. Kaitlyn told police that Kevin had called her mother earlier in the day and asked to see her. She also said Kevin carries a folding knife on his person.

On Saturday morning, police found Kevin Justin McGuigan in a Rockville gas station and took him into custody.

He made his first court appearance in Montgomery County District Court on Monday, December 31, 2018 where a Judge ordered him held in custody and to be examined for his mental health with a new bail review hearing in another week.



Kevin Justin McGuigan, formerly of 4 Marwood Court, Rockville, Md., and more recently living in North Bethesda, was charged by Montgomery County, Md., Police Detective Mike Kwarciany on Dec. 29, 2018 with first-degree murder in the homicide of his mother Jaclyn McGuigan.  A preliminary hearing is set for Jan. 25, 2019. While McGuigan awaits his court appearance, he is being held in the Montgomery County Jail.

DWI HIT PARADE Copyright 2018

McGuigan’s most recent visit to a courtroom took place in Worcester County, Md., when he appeared to face traffic and DWI charges he accumulated on September 7, 2018 in Ocean City, Md.

Kevin McGuigan was arrested by Maryland State Trooper Ruiz as he operated a 2005 Honda Civic on Coastal Highway southbound at 23rd Street. The charges, nearly a dozen, included driving while suspended, reckless driving, reckless endangerment, tailgating, and blowing through red traffic lights were all put on the Stet Docket. With Attorney Charles Coburn representing him in Ocean City District Court, McGuigan entered into a plea deal on Oct. 24, 2018, with Worcester County States Attorney Bill McDermott that put two of the DWI charges on the Stet Docket and McGuigan entered a guilty plea to DWI per se. THE DEAL: In return for the guilty plea, McGuigan became a guest of the Worcester County taxpayers in the county jail for twenty days. A fine of $557.50 was assessed but the payment was deferred until Jan. 31, 2019, which now will have to be collected from his eventual inmate funds earned by making license plates in the Maryland House of Corrections.

Why did McGuigan get sentenced to twenty days in jail in October? Because he was sentenced to sixty days in jail in a plea deal On Sept. 6, 2018, with States Attorney McDermott, who failed to win reelection as the county’s prosecutor in 2018’s Republican Primary. States Attorney McDermott allowed McGuigan to have his sentence of sixty days in jail to be suspended. Therefore, with payment of a  fine of $307.50, he was able to walk away a free man and return to Ocean City for another romp through town while driving drunk just two months later. To show his appreciation to the feckless prosecutor for his sweet deal from his arrest on July 4, 2018 by Ocean City Police Officer Neshawn Jubilee, he went out driving drunk the next day when he was caught by Trooper Ruiz at 11:04 pm on Sept. 7, 2018. The voters must have had a clue as to States Attorney McDermott being a less than stellar example of a prosecutor determined to protect the public when they voted him out in the primary election.
