SAN DIEGO – The estranged wife of a biotech executive, who allegedly shot and wounded two La Jolla men, including her brother, at homes about a half-mile apart early Wednesday, spoke to Fox5.

Bonnie Fletcher said her relationship with her soon-to-be ex-husband Hans Petersen, 49, was wonderful until he was fired from a job.

“He didn’t take it very well,” said Fletcher, adding that he turned to alcohol and became abusive. “You have this fabulous and wonderful husband who you love and adore… then things get a little different and a little strange.”

Bonnie-Fletcher,-Hans-PetersenPetersen was arrested Wednesday morning after he opened fire into a home from a yard in the 5700 block of Waverly Drive about 3 a.m., wounding a 53-year-old man who awoke along with his wife in their bedroom to the sound of gunshots and got up to see what was happening, according to San Diego police.

The victim suffered a bullet wound to his abdomen, San Diego Police Department public affairs Lt. Kevin Mayer said. The woman was unhurt.

Nearly four hours later, more gunfire erupted in the 1400 block of Cottontail Lane, about a half-mile northeast of the site of the first shooting. There, police found a 43-year-old resident with a gunshot wound to his torso and Petersen 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 wrestle the gun away from the assailant and hit him over the head with it, subduing him. The intruder apparently had gained entry to the house by breaking a window with a rock, the lieutenant said.

Medics took the two 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.

Fletcher’s two young daughters were home when he was shot, according to police. Neither was harmed. He was in stable condition and is expected to make a full recovery.

“[Hans] was obviously trying to find me,” Bonnie Fletcher said. “My brother literally took a bullet in the gut for me, protecting me and keeping his daughters safe.”

The suspect was treated at the same hospital before being released and taken to downtown SDPD headquarters for questioning, Mayer said.

Petersen was booked into San Diego Central Jail in the late afternoon on suspicion of burglary, firing a gun into an occupied dwelling, discharging a firearm causing great bodily injury and three counts of attempted murder. He was being held without bail pending arraignment, scheduled for Friday afternoon.

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.
