An argument at a 2-year-old's birthday party Saturday in Maryland led to a shooting that wounded seven people.

According to local reports, the argument broke out outside an apartment complex in Camp Springs, located less than 20 miles southeast of Washington, D.C. Three of the individuals hurt in the incident were said to be in serious condition, while the other four were said to be in more stable condition. All were adults between the ages of 18 and 20 and all are expected to survive.

Prince George County Police Chief Hank Stawinski explained that an individual approached the party, where “words were exchanged” prior to shots being fired. There were 12 people in attendance at the party, according to reports.

The shooter has not yet been taken in by police and remains at large.

A description of the suspect has not been given, but police currently believe the gunman acted alone.

The shooting comes after Prince George’s County Police in May found a 28-year-old man who had been shot on the sidewalk.
