JEFFERSON COUNTY, Colo. — A man was arrested Wednesday after allegedly attacking another man with a hatchet inside a Jefferson County home.

The Jefferson County Sheriff’s Office (JCSO) said deputies were called to a disturbance at a home in the 3400 block of Burnham Drive around 8:45 p.m. Wednesday.

According to the sheriff’s office, a neighbor called 911 after an interaction with a man later identified as 35-year-old Bradley Lindsey. JCSO said Lindsey was walking down the street when he told the neighbor to “call the police if they heard gunshots.” The alarmed neighbor immediately called the authorities.

Deputies arrived to find Lindsey covered in blood, as well as an injured 61-year-old man who required medical attention. The sheriff’s office said Lindsey allegedly attacked the man with a hatchet.

According to JCSO, the 74-year-old homeowner said he didn’t know Lindsey but let him in when he knocked on the door. During one conversation, Lindsey allegedly made remarks about “taking care” of the 61-year-old.

The 61-year-old man had been living with the 74-year-old homeowner as a tenant for several years, according to the sheriff’s office. JCSO said the homeowner is currently in the process of legally evicting the 61-year-old tenant.

The sheriff’s office did not elaborate on the relationship, if any, between Lindsey and the victim.

The 61-year-old man was treated at hospital for serious injuries and later released. Lindsey was booked into the Jefferson County Jail on suspicion of attempted first-degree murder.

The investigation is ongoing, according to the sheriff’s office.
