The estranged son of Harford County cop killer told WBAL his mother alerted authorities David Evans was at Panera in Abingdon.

ABINGDON, MD – The son of the gunman who killed two deputies Wednesday in a confrontation that started in Panera said it was not the first time his father shot someone.

Jeremy Evans told WBAL that his estranged father—68-year-old David Brian Evans—shot his mother in 1997 or 1998 and they had not seen him in the nearly 20 years since the bullet traveled in and out of her neck.

Upon hearing from her sons that he may have been spotted in Harford County and was at the Panera in Abingdon, she went to the restaurant to see for herself, then alerted the sheriff’s office that she thought there was a warrant out for his arrest and was afraid he was going to hurt her, according to Jeremy Evans.

There were at least two warrants out for the arrest of David Evans, one in Florida for assaulting a police officer and eluding arrest, and a civil writ through the Harford County Circuit Court, the sheriff’s office said in a statement.

At 11:46 a.m., deputies responded to Panera in the 3400 block of Merchant Boulevard based on a tip that David Evans was there, according to Harford County Sheriff Jeffrey Gahler.

When a deputy approached David Evans in the restaurant, witnesses said he was immediately shot.

A 15-year-old who was sitting nearby with her mother told the Associated Press: “I saw him fall back out of his chair, and the blood started coming out.” She was one of several young people at the restaurant for lunch on a day when school had been canceled in Harford County due to icy conditions.

The teen’s mother said the shooter seemed experienced, stating: “He knew what he was doing with a gun because he shot directly into the head.”

In fact, his son said that David Evans had been in the Army and probably shot the officer to avoid going to jail.
