Editor’s note: This story has been corrected to reflect that Michael Brittain was ordered to pay $120,000 to Allyson Stone. She was not ordered to pay him money.

Lafayette police consider the ex-husband of the Lafayette woman badly burned by a bomb on Saturday afternoon a “person of interest,” according to media reports.

Denver news stations reported that police named Allyson Stone’s ex-husband, 50-year-old Michael Anthony Brittain, a person of interest in the case after police executed a search warrant on the man’s Thornton home on Saturday night. A Lafayette sergeant refused Sunday night to confirm the report.

Brittain isn’t in police custody, according to the news stations, and wasn’t listed as a Boulder County Jail inmate. The two children he had with Allyson Stone were removed from his home and placed with a family friend in Lafayette, neighbors said.

Police said Sunday that the device that exploded was inside a paper bag with the names of Allyson Stone, 44, and her current husband, Christopher Stone, 59, written on the outside.

The crime remains under investigation and no other details about the device were provided.

According to police, the couple walked out of their home at 337 Lodgewood Point just before 12:56 p.m. Saturday when they saw a package “described as a paper bag with their names on it next to their car.”

Allyson Stone picked up the package and put it in their gray Volvo as they left their home, en route to Boulder.

Christopher Stone told police they had driven about a block and were mid-block on Ravenwood Lane when his wife began to open the package, setting off “some kind of explosive device that severely burned both of them,” Lafayette police Cmdr. Gene McCausey said in a news release.

Neighbor Chad Seidel said he heard a commotion and went outside to find a car with smoke spewing out of the front and passenger doors in front of his house. He said there were no flames, causing speculation among the neighbors that the explosion set off a chemical fire.

“It smelled like a firework had gone off in the car,” he said.

He said he turned off the ignition, found the victims outside another house and stayed near the car to direct emergency personnel to their location.

The couple was taken to Exempla Good Samaritan hospital in Lafayette and then to a burn unit at an undisclosed location with serious injuries.

According to a brief statement released by the family on Sunday, Allyson Stone remains in serious condition. Christopher Stone was treated and released.

“This was a horrible act of violence which has left friends and family alike shaken and emotionally hurt,” one of Allison Stone’s friends, Olney Kliewer, wrote on Facebook.

Court records show that police issued Brittain a summons in a domestic violence case in may 2003. He was arrested in August 2003 on charges of misdemeanor assault, harassment and two counts of child abuse.

Stone, then Allyson Brittain, filed for divorce three days after his arrest.

The harassment and child abuse charges were dismissed by the district attorney, while Brittain was found not guilty of the assault charge by a jury. The couple’s divorce was finalized in 2004, but the judge issued a judgement in February last year that Brittain owed Stone about $120,000, according to court records.

Court records also show that a 63-year-old Boulder County woman also was successful in getting a judge to impose a permanent restraining order against Brittain in 2007, though the reason the woman asked for the restraining order wasn’t available.

Following the explosion on Saturday, Boulder County dispatchers initiated an automated 911 call to the neighborhood about the incident. About 20 homes in the immediate vicinity of the car were evacuated as investigators spent the next eight hours securing the vehicle.

In 2010, Allyson Stone made headlines when she was involved in an incident in which she was bitten by a dachshund named Spork while she was working as a veterinary technician at Lafayette’s Jasper Animal Hospital. Spork was to have been euthanized after the attack, but a municipal judge spared the dog.

Lafayette police have said they don’t believe the bombing is related to the Spork case.
