MIAMI -

A Friday morning shooting in Miami that left one person in critical condition is the latest in a series of violent crimes this summer, and police are trying to figure out whether they are connected. 

Just before dawn Friday, surveillance video showed police speeding to the scene where someone shot bullets into a car at Northwest 24th Avenue and Northwest 37th Street.

"When we got there, we discovered one person who was very critically injured," said Maj. Delrish Moss, of the Miami Police Department. 

The passenger was shot in the chest and later died. The driver was shot in the leg and survived. 

No arrests have been made. 

"The other car approached, fired shots and sped away," Moss said. 

The incident was the latest in a series of drive-by shootings in Miami-Dade County. Three days ago, one man was killed in a shooting involving a white car near a North Miami Beach store. 

On the same day, in Miami, two men were shot during another drive-by. Police were serving a warrant when two men in a silver SUV started shooting. The two victims in that case survived. 

Three days before that, three people were shot in drive-by shooting at a Miami Lakes traffic light. Those victims also survived. 

"Crime doesn't necessarily know jurisdiction," Moss said. "What we've done is we've met with a number of jurisdictions -- the county, Miami Gardens, a number of police departments that have had issues of late -- and we're comparing notes to see if there's a connection."
