A 37-year-old Concord realtor who espoused anti-Trump sentiments online is being held for allegedly keying dozens of cars during the recent state GOP convention as police found a disturbing cache of guns, zip ties, and suicide notes in his apartment.

Lawrence Anthony Dunlap of South Spring Street was arrested and charged Friday with 11 felonies for the incident that took place earlier this month.

The investigation into Dunlap’s connection to the vandalism became intense Friday when Concord Police issued a “be on the lookout” alert for Dunlap over concerns for his safety and the safety of police who might encounter him, according to reporting by Tony Schinella at the Concord Patch.

Dunlap was reportedly seen leaving his home on foot Friday morning. Police report finding guns, a manifesto, suicide notes, and a bag containing zip ties, masks, and gloves.

Dunlap’s social media profiles were largely scrubbed Friday. But some remaining posts indicate an antipathy for former President Donald Trump and Trump’s supporters. In a rambling Facebook post accusing Trump voters of racism and law enforcement of denying the events of Jan. 6, 2021, Dunlap called Trump a dictator before oddly calling for unity.

“Y’all (Trump supporters) lost your s–t when [Obama] tried to fix healthcare. Never mind the sheer f—ery Trump has pulled for the last for [sic] years,” Dunlap posted.

“Then to tell me a dictatorship by Trump is better than the democracy we know. Kinda say [sic] it all now doesn’t it,” Dunlap added. “As long as we elect people who chose to divide [sic] over unify we will never get anything done.”

Dunlap is registered as an unaffiliated voter. He is accused of riding a skateboard around the cars parked for the state GOP convention and keying them as the car owners were inside.

Di Lothrop, a Nashua Republican whose car was damaged during the GOP convention held at Concord High School, is heartened by news of an arrest, but unnerved by Dunlap’s alleged motives.

“Now that is sick,” Lothrop said.

As a Trump campaign volunteer during the primary, Lothrop met a lot of Nashua residents who were not fans of the former president when she knocked on doors. Most were polite, but Lothrop did have an unsettling encounter with one anti-Trump Nashua resident making threats.

“He told me I had three seconds to get off his property or he would drop me,” said Lothrop, who is in her 70s.

The man followed up that threat by getting close to Lothrop and counting, she said.

“It is what it is. People like that are sick. There’s nothing you can really do or say to them to change their minds,” Lothrop said.

“I’m appreciative of the professionalism displayed by the Concord Police,” said state GOP Chairman Chris Ager.

Dunlap is being held on preventative detention and is due in Merrimack Superior Court on Monday. He’s charged with 11 felony counts of criminal mischief.
