A Baker man accidentally shot and killed his girlfriend early Sunday while shooting at his brother's dog after the two men argued, according to an affidavit filed by the Baker Police Department.

Rhykem Rogers, 27, was arrested after he shot and killed his girlfriend Cherish Faith Smith, 23, around 4:30 a.m. in the 2400 block of McHugh Road, his arrest report says.

Rogers had been out with his brother and mother drinking and returned with his brother just before 4 a.m. to the couple's home on McHugh Road, where his brother often stayed, the report says. The two men then got into a heated argument, with Rogers demanding his brother leave.

Rogers then released his brother's pit bull from the backyard and began shooting at the dog with a semi-automatic handgun as the dog ran across the street, the report says. Rogers fired 4 or 5 rounds, missing the dog but accidentally hitting Smith.

Smith, who was shot in the stomach, died of her injuries at a hospital, the report says. She had given birth to the couple's daughter just three weeks ago.

Authorities could not confirm the exact relationship between Rogers and Smith on Sunday night, but court filings from 2016 refer to Smith as Rogers' girlfriend.

Police later found a black .9mm semi-automatic handgun across the street from Rogers and Smith's address, which Rogers told detectives was his.

Rogers was also booked for a May motor vehicle crash in which he and a Baker Police officer hit each other, with the impact injuring the officer. A blood test found Rogers' blood alcohol level at the time of the crash was 0.22, almost three times the legal limit, according to that police report.

Rogers, 2421 McHugh Road, Baker, was booked Sunday night on counts of negligent homicide, illegal use of weapons and DWI.
