On what was supposed to be a festive Fourth of July, residents of the Kingsessing section were instead trying to make sense of five people killed and two others injured during what city leaders called an unimaginably disgusting and horrifying shooting spree. The suspect in the attack, 40-year-old Kimbrady Carriker, was arraigned on murder charges and several other offenses in a Philadelphia courtroom Wednesday and will be denied bail as the case moves through the courts.

In a video statement, authorities said that Carriker had been acting agitated in the days leading up to the killings and had worn a bulletproof vest around his house. He had also posted disturbing material online, prosecutors said. They were awaiting medical records to determine whether he had suffered any mental health issues.

Police say that when they arrived at the shooting scene, they found victims with gunshot wounds and started to tend to them when they heard more shots. Some officers ran toward the gunfire and chased the suspect, who eventually cornered himself in an alley, police Commissioner Danielle Outlaw said Tuesday afternoon. Six people were transported to Penn Presbyterian Medical Center, where four were pronounced dead.

The victims were identified as 20-year-old Lashyd Merritt, 29-year-old Dymir Stanton, 59-year-old Ralph Moralis, 15-year-old Daujan Brown, and 31-year-old Joseph Wamah Jr. Two children, ages 2 and 15, were also shot, with one suffering a leg injury and the other getting glass in his eyes from a window shattered by gunfire.

At a news conference Tuesday, Outlaw called the killings "unimaginably disgusting and horrifying," saying the shooter had no connection to any of the victims and appeared to be firing randomly. She described Carriker as a "deranged individual."

Investigators have not determined a motive, but Outlaw said the suspect was likely angry about something that happened in his life and was seeking revenge. She praised the bravery of officers who ran toward the gunfire to save lives and caught the suspect.

Several blocks from where the mass shooting occurred, neighbors spent the morning making sure their lawns were mowed, and their children were in school. They also attended a vigil to remember the victims of Monday night’s shooting spree.

Philadelphia District Attorney Larry Krasner has charged 40-year-old Kimbrady Cariker with five counts of murder in connection to the deadly shooting rampage. The alleged shooting spree left two children, a toddler and an infant, wounded, including a 2-year-old who was taken to the hospital with a leg injury from bullets fired at the family.

The slayings came on a night that was supposed to be filled with joyous Fourth of July celebrations and a sense of security after a month without mass violence in the city. But in a neighborhood with more than its share of gun violence, officials, relatives, and stunned residents were left to spend the holiday trying to figure out why. The shooting sparked outrage and concern across the country, particularly among parents concerned for their safety and that of their children.
