Maryland Man Killed Himself After Shooting 5 People, Police Don't Know Why

A Maryland man shot his parents dead at their house and then gunned down two people and wounded one at a convenience store Sunday. After that, he set his apartment on fire before ending his life. Authorities are still clueless as to what led him to commit the murders.

Joshua Green, 27, used a legally registered gun that he bought in 2020 when he went on a shooting spree Sunday, killing four people and injuring one, Baltimore County Police Col. Andre Davis said at a news conference Monday.

"As to why this occurred, we have no idea yet," Davis said, adding that homicide detectives were trying to figure out the motive. Police believe Green had no accomplices.

Green first shot and killed his parents while they were in their Baltimore County home. He then drove to a Royal Farms store in Essex around 7 a.m. Sunday. At the parking lot, Green fatally shot a woman who was inside her car. After that, he went into the store, where he killed a customer who was standing by the cash register. He also shot and wounded an employee of the store. The store employee was taken to a hospital and was in stable condition, police said.

Green later went to his apartment and set it on fire before he shot himself. Police discovered Green dead in the parking lot of his apartment with a self-inflicted gunshot to the head. The apartment was engulfed in flames.

Homicide detectives found the bodies of Green's parents when they went to the home to inform them about their son's death.

Police said they were getting "more questions than answers" about the shooting.

"Our investigators will continue to work tirelessly to investigate this incident to piece details together and as additional information becomes available, we will continue to provide updates to the public. For now, we know that four innocent people lost their lives and one person sustained serious injuries," Police Chief Melissa Hyatt said at the same news conference.
