A man armed with a machete was shot and killed in an officer-involved shooting in City Heights Sunday.
Neighbors heard gun shots around 10:20 p.m. near the home on Menlo Avenue near Landis Street.
One person thought the noise was leftover fireworks from the Fourth of July but realized in the morning when he saw caution tape outside his window that something bad had happened
A man inside the home was threatening to kill his family members with a knife and a stick, officials said.
The 21-year-old resident made threats to kill police officers, investigators told NBC 7. Family members have identified him as Ja Ma Lo Day.
When the man swung the machete at an officer, two officers opened fire and struck the suspect several times killing him.
A police dog named Nando required stitches from a machete wound but was expected to survive. As of 10 a.m., the K-9 was out of surgery and resting at home, officials said.
The 8-year-old German Shepherd was set to retire this month, officials said.
Day came to the U.S. six years ago as a refugee from Burma, his family told NBC 7.
His brother said Day's mother died of cancer last year.
Day also has had his share of troubles including previous arrests, drug use and mental issues, according to his brother.
Court documents obtained by our NBC Investigates unit reveal, Day was arrested last October, for allegedly threatening and assaulting his brother with a knife. Both charges are felonies.
Court records indicate his lawyer raised questions about Day's mental state, and he was evaluated by a court-appointed doctor.
In January, a Judge ruled that Day was mentally competent to stand trial.
But on January 31st, the two felony charges were dismissed for lack of evidence, and Day was released from jail.
Investigators said officers attempted to use tasers before firing on the suspect.
The San Diego Police Deparment identified the officers involved as Officer Kelly J. Copeland Jr. -- a six-and-a-half-year vet of the department -- and Officer Javier M. Morales, a five-and-a-half-year vet.
