SAN DIEGO — A San Diego biotech executive who allegedly shot and wounded two La Jolla residents, including a former business partner, at homes about a half-mile apart early Wednesday was arrested following a scuffle with the second victim, authorities reported.

bird-rock-shooting-locationHans Peterson, 48, is suspected of opening fire into a home in the 5700 block of Waverly Drive about 3 a.m., wounding a 53-year-old man who had been awakened by the gunshots and got up to investigate, according to San Diego police.

The victim suffered a bullet wound to his upper body, SDPD public- affairs Lt. Kevin Mayer said.

Shortly before 7 a.m., more gunfire was reported in the 1400 block of Cottontail Lane, about a half-mile southwest of the site of the first shooting. There, police found a 43-year-old resident with a gunshot wound to his upper body and Peterson suffering from a head injury, Mayer said.

The victim, the suspect’s former brother-in-law, told officers that after being shot in the abdomen, he managed to wrest the gun away and the assailant him over the head with it.

Medics took the gunshot victims, both of whom were expected to survive, to Scripps Memorial Hospital La Jolla. Police withheld their names, but neighbors identified the initial victim as UC San Diego researcher Steven Dowdy and the second as Mission Beach-based real estate agent and property investor Ron Fletcher.

Peterson was treated at the same hospital before being released and taken to downtown SDPD headquarters for questioning. He was expected to be booked into county jail later in the day, Mayer said.

The relationship between Dowdy and the suspect was unclear, though the residents of both homes involved in the shootings are acquainted, the lieutenant said.

According to Petersen’s online career profile on the LinkedIn website, he previously served as chief executive officer of Traversa Therapeutics, a now- bankrupt Sorrento Valley biopharmaceutical company that lists Dowdy as a founder and board member. The two men parted ways following a falling-out that spawned a lawsuit, Fletcher told Fox5.

According to Petersen’s online resume, he is CEO of Bays Four Corp., a genome data-analysis firm headquartered in La Jolla.

Two young girls were in Fletcher’s home at the time of the shooting, according to police. Neither was harmed, Mayer said.
