STOCKTON — An exceptional number of reported gun incidents kept police officers on the move throughout the city Sunday afternoon into early Monday. But fortunately only two gunshots were fired in one of the incidents and no one was reported injured.

The crimes included robbery, a shot fired into a vehicle, several people caught with firearms who should not have had them and a violent boatjacking, according to police. Four arrests were made.

A few minutes before 4 p.m. Sunday, officers attempted to make a traffic stop in northwest Stockton but instead, the suspect vehicle sped away before stopping somewhere between Hickock Drive and Cody Way, northeast of Thornton and Wagner Heights roads.

At that point, a passenger fled from the vehicle, discarding a backpack as he ran.

A pursuing officer caught up to the suspect, forced him to the ground and took him into custody. After the backpack was recovered, officers discovered two loaded .40-caliber handguns with extended magazines and arrested Kendrell Guyton, 19, and a male juvenile on suspicion of weapon charges and resisting arrest.

The boatjacking occurred about 8 p.m. in the 1100 block of Rosemarie Lane, just east of Pershing Avenue.

The victim was in a parking lot when two robbers approached him from behind. One of the robbers, armed with a handgun, struck the victim on the back of the head with the gun, then held him at gunpoint while his accomplice hooked the boat trailer holding a white-and-tan 1980 Avenger fishing boat to their older white pickup, according to police.

Both robbers then got into the pickup and fled on Rosemarie, towing the stolen boat behind them. The victim declined medical attention at the scene. The trailer had California license 4PK7152.

Police did not provide a description of the robbers.

At about 1:10 a.m. Monday in northeast Stockton, officers checked out a man in a parking lot at McNair High School in the 9500 block of Ronald E. McNair Way and allegedly discovered a loaded 9 mm handgun in the man’s vehicle. The officers arrested Jordan Burston, 32, on suspicion of weapon charges.

Back in northwest Stockton, a man and woman were talking about 2:50 a.m. on Stacey Court near Waudman Road, west of Davis Road, when the man asked the woman for money and she told him she didn’t have any. At that point, the man brandished a black handgun and demanded the woman’s purse, police reported.

The woman complied, handed over her purse and the robber, known to the woman as a 35-year-old man, got into a black sedan and fled the scene, according to police.

The night’s final two gun crimes were reported simultaneously to police at 3:20 a.m. in opposite corners of the city.

Two people were arguing about something in southeast Stockton when one of them decided to fire one gunshot into the air and a second gunshot into the victim’s vehicle parked in the 1000 block of Burkett Avenue, northwest of South Golden Gate Avenue and East Dr. Martin Luther King Jr. Boulevard.

In northwest Stockton in the 9300 block of Thornton Road, just south of Wagner Heights Road, officers checked out a man and found him allegedly in possession of a loaded .45-caliber handgun. The officers arrested Rico Ruiz-Altamirano, 29, without incident on suspicion of weapon charges and an unspecified warrant, according to police.
